java.lang.Objectipworksssl.Https
public class Https
The HTTPS Bean can be used to retrieve documents from the World Wide Web.
The HTTPS Bean is the SSL-enabled equivalent of the IP*Works! HTTP bean. The main difference is the introduction of a set of new configuration settings, properties and events that deal with SSL security. The ipworksssl.Https#config and {@link ipworksssl.Https#config configuration settings determine which protocols are enabled and at what security level. The {@link ipworksssl.Https#getSSLCert SSLCert} property is used to select a client certificate if the server is requesting client authentication. The {@link ipworksssl.Https#config configuration setting, together with the {@link ipworksssl.HttpsSSLServerAuthenticationEvent SSLServerAuthentication} event allow you to check the server identity and other security attributes. Finally, the {@link ipworksssl.HttpsSSLStatusEvent SSLStatus} event provides information about the SSL handshake.
The HTTPS Bean implements a standard HTTP client through a simple plug-and-play interface as defined in RFCs 1945 and 2616 with the added option of SSL security.
The bean contains a number of properties that map directly to HTTP request headers. Files are received through events: {@link ipworksssl.HttpsTransferEvent Transfer} for contents, and {@link ipworksssl.HttpsHeaderEvent Header} for HTTP headers. The {@link ipworksssl.HttpsStartTransferEvent StartTransfer} and {@link ipworksssl.HttpsEndTransferEvent EndTransfer} events are fired at the beginning and end of transmission.
To receive a document call the {@link ipworksssl.Https#get Get} method with the URL parameter. Data can be POST-ed to the HTTP server by assigning it to the {@link ipworksssl.Https#getPostData PostData} property and then calling the {@link ipworksssl.Https#post Post} method.
The PUT method is also supported. You should specify the {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} properties or alternatively the {@link ipworksssl.Https#config and call the {@link ipworksssl.Https#put Put} method with the specified URL . The {@link ipworksssl.Https#getAttachedFile AttachedFile} will be sent to the server.
The HTTPS Bean supports the HTTP Basic authentication scheme through the {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} properties. Other authentication schemes can be implemented by using the {@link ipworksssl.Https#getAuthScheme AuthScheme} property.

public java.lang.String getAccept()
If this property contains a non-empty string, an HTTP Accept header is added to the request.
The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.
public void setAccept(java.lang.String accept)
throws IPWorksSSLException
If this property contains a non-empty string, an HTTP Accept header is added to the request.
The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.
IPWorksSSLExceptionpublic boolean isAllowHTTPCompression()
This property enables HTTP compression for receiving data. When set to true, the bean will accept compressed data. It will then uncompress the data it has received. The bean will handle data compressed by both GZIP and Deflate compression algorithms.
When true, the bean adds an "Accept-Encoding" header to the outgoing request. The value for this header can be controlled by the ipworksssl.Https#config config. The default value for this header is "gzip, deflate".
{@link ipworksssl.Https#getTransferredData TransferredData} will contain the decompressed data received by the server, but the {@link ipworksssl.HttpsTransferEvent Transfer} event will report exactly what is received by the server (compressed data).

IPWorksSSLExceptionpublic java.lang.String getAttachedFile()
PostData if the POST or PUT methods are used.
If this property contains a non-empty string, then if the HTTP 'POST' or 'PUT' methods are used (through the Post or Put methods), the contents of this property are appended to the HTTP request after any data in PostData .
An HTTP 'Content-Length' header is also added to request. Its value is the cumulative length of the PostData string and the file.
If you are attempting to upload a file to a receiving script, this property must be MIME encoded, or you should use the WEBUPLOADS component.
public void setAttachedFile(java.lang.String attachedFile)
throws IPWorksSSLException
PostData if the POST or PUT methods are used.
If this property contains a non-empty string, then if the HTTP 'POST' or 'PUT' methods are used (through the Post or Put methods), the contents of this property are appended to the HTTP request after any data in PostData .

If you are attempting to upload a file to a receiving script, this property must be MIME encoded, or you should use the WEBUPLOADS component.
IPWorksSSLExceptionpublic java.lang.String getAuthorization()
If the Authorization property contains a non-empty string,
an Authorization HTTP request header is added to the
request. This header conveys Authorization information to the
server.
A common use for this property is to specify OAuth authorization string.
This property is provided so that the HTTP bean can be extended with other security schemes in addition to the authorization schemes already implemented by the bean.
The AuthScheme property defines the authentication scheme used.
In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded,
and the result is put in the Authorization property
in the form "Basic [encoded-user-password]".
public void setAuthorization(java.lang.String authorization)
throws IPWorksSSLException
If the Authorization property contains a non-empty string,
an Authorization HTTP request header is added to the
request. This header conveys Authorization information to the
server.
A common use for this property is to specify OAuth authorization string.
This property is provided so that the HTTP bean can be extended with other security schemes in addition to the authorization schemes already implemented by the bean.
The AuthScheme property defines the authentication scheme used.
In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded,
and the result is put in the Authorization property
in the form "Basic [encoded-user-password]".
IPWorksSSLExceptionpublic int getAuthScheme()
This property will tell the bean which type of authorization to perform when the User and Password properties are set.
This property should be set to authNone (3) when no authentication is to be performed.
By default, this property is authBasic (0), and if the User and Password properties are set, the bean will attempt basic authentication. If AuthScheme is set to authDigest (1), authNtlm (4) or authNegotiate (5), digest, NTLM or Negotiate authentication will be attempted instead.
If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through Authorization property.
If AuthScheme is set to authOAuth (6) then the authorization string must be supplied through Authorization property.
Note that, if you set the Authorization property and AuthScheme is not authProprietary or authOAuth, the AuthScheme will be set automatically to authProprietary (2) by the control.
For security purposes, changing the value of this property will cause the bean to clear the values of User , Password and {@link ipworksssl.Https#config .
public void setAuthScheme(int authScheme)
throws IPWorksSSLException

IPWorksSSLExceptionpublic boolean isConnected()
This property is used to determine whether or not the bean is connected to the remote host.
public void setConnected(boolean connected)
throws IPWorksSSLException
This property is used to determine whether or not the bean is connected to the remote host.
IPWorksSSLExceptionpublic java.lang.String getContentType()
If this property contains a non-empty string, a Content-Type HTTP request header is added to the request. The purpose of the header is to show the contents
of the data during a Post or Put to the server.
The most common example is posting of HTML form input data. In that case, this property must be set to "application/x-www-form-urlencoded" .
public void setContentType(java.lang.String contentType)
throws IPWorksSSLException
If this property contains a non-empty string, a Content-Type HTTP request header is added to the request. The purpose of the header is to show the contents
of the data during a Post or Put to the server.
The most common example is posting of HTML form input data. In that case, this property must be set to "application/x-www-form-urlencoded" .
IPWorksSSLExceptionpublic HTTPCookieList getCookies()
This property contains a collection of cookies. To add cookies to outgoing HTTP requests, add cookies (of type httpcookie ) to this collection.
To see cookies that are set by the server, use the SetCookie event, which displays the cookies and their properties as set by the server.
Those cookies are also added to Cookies .
{@link ipworksssl.Https#config can be used to control the maximum number of cookies saved.
This collection is indexed from 0 to size - 1.
public Firewall getFirewall()
This is a Firewall type property which
contains fields describing the firewall
through which the bean will attempt to connect.
public void setFirewall(Firewall firewall)
throws IPWorksSSLException
This is a Firewall type property which
contains fields describing the firewall
through which the bean will attempt to connect.
IPWorksSSLExceptionpublic int getFollowRedirects()
This property determines what happens when the server issues a redirect. Normally, the bean returns an error if the server responds
with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.
If this property is set to frSameScheme (2), the new URL is
retrieved automatically only if the URLScheme is the same, otherwise
the bean throws an exception.
Note that following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server and port are different than
the existing one, User and Password are also reset to empty,
unless this property is set to frAlways (1), in which case
the same credentials are used to connect to the new server.
A Redirect event is fired for every URL the product is redirected
to. In the case of automatic redirections, the Redirect event is
a good place to set properties related to the new connection (e.g. new
authentication parameters).
The default value is frNever (0). In this case, redirects are never followed, and the bean throws an exception instead.
public void setFollowRedirects(int followRedirects)
throws IPWorksSSLException

IPWorksSSLExceptionpublic java.lang.String getFrom()
This property contains the email address of the HTTP agent (optional). If it contains a non-empty string, an HTTP From: header is added to the request. This header generally gives the email address of the requester of the document.
public void setFrom(java.lang.String from)
throws IPWorksSSLException
This property contains the email address of the HTTP agent (optional). If it contains a non-empty string, an HTTP From: header is added to the request. This header generally gives the email address of the requester of the document.
IPWorksSSLExceptionpublic java.lang.String getHTTPMethod()
This property contains the HTTP method used for the request. If an empty string is provided, the HTTPMethod is determined automatically by the method being called. You may change it to a custom value if you require an HTTP method other than what is provided by the bean.
public void setHTTPMethod(java.lang.String HTTPMethod)
throws IPWorksSSLException
This property contains the HTTP method used for the request. If an empty string is provided, the HTTPMethod is determined automatically by the method being called. You may change it to a custom value if you require an HTTP method other than what is provided by the bean.
IPWorksSSLExceptionpublic boolean isIdle()
Idle will be False if the component is currently busy (communicating
and/or waiting for an answer), and True at all other times.
public java.lang.String getIfModifiedSince()
If this property contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the bean throws an exception
The format of the date value for IfModifiedSince is detailed
in the HTTP specs. An example is Sat, 29 Oct 1994 19:43:31 GMT.
public void setIfModifiedSince(java.lang.String ifModifiedSince)
throws IPWorksSSLException
If this property contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the bean throws an exception

If this property is empty then the received data is provided through TransferredData and the Transfer event.
public void setLocalFile(java.lang.String localFile)
throws IPWorksSSLException
This property is used when getting a document.
If this property is empty then the received data is provided through TransferredData and the Transfer event.
IPWorksSSLExceptionpublic java.lang.String getLocalHost()
The LocalHost property contains the name of the local host
as obtained by the gethostname() system call, or if the
user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the bean initiate connections (or accept in the case of server beans) only through that interface.
If the bean is connected, the LocalHost property shows
the IP address of the interface through which the connection
is made in internet dotted format (aaa.bbb.ccc.ddd). In most
cases, this is the address of the local host, except for multi-homed
hosts (machines with more than one IP interface).
NOTE: LocalHost is not persistent. You must always set it in
code, and never in the property window.
public void setLocalHost(java.lang.String localHost)
throws IPWorksSSLException

IPWorksSSLExceptionpublic HeaderList getParsedHeaders()
This property contains a collection of headers returned from the last request. Whenever headers are returned from the server, the headers are
parsed into a collection of headers. Each header in this collection contains information describing that header.
{@link ipworksssl.Https#config can be used to control the maximum number of headers saved.
This collection is indexed from 0 to size - 1.
public java.lang.String getPassword()
This property contains a password if authentication is to be used. If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded and the result is put in the ipworksssl.Https#config config setting in the form "Basic [encoded-user-password]".
If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to HTTP Digest Authentication, the {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} properties are used to respond to the HTTP Digest Authentication challenge from the server.
If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to NTLM, NTLM authentication will be attempted. If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to NTLM and {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} are empty, the bean will attempt to authenticate using the current user's credentials.
public void setPassword(java.lang.String password)
throws IPWorksSSLException
This property contains a password if authentication is to be used. If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded and the result is put in the ipworksssl.Https#config config setting in the form "Basic [encoded-user-password]".
If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to HTTP Digest Authentication, the {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} properties are used to respond to the HTTP Digest Authentication challenge from the server.
If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to NTLM, NTLM authentication will be attempted. If {@link ipworksssl.Https#getAuthScheme AuthScheme} is set to NTLM and {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} are empty, the bean will attempt to authenticate using the current user's credentials.
IPWorksSSLExceptionpublic byte[] getPostData()
If this method is a non-empty string, then if the HTTP Post method is used. The contents of this property are appended to the HTTP request after the HTTP headers.
An HTTP 'Content-Length' header is also added to the request. Its value is the length of the string in PostData , or, if the AttachedFile property has been set, the cumulative length of the string and the file. See the description of the AttachedFile property for details.
If the goal is to upload a file or binary form data to a receiving script, the postdata must be MIME encoded. The WebUpload component is specifically designed for this and will perform all of the MIME encoding for you automatically. The WebForm component can be used for any form data posting.
The most common example is posting of HTML form input data. In that case, the ContentType property must be set to "application/x-www-form-urlencoded".
Example (Performing a Post)

public java.lang.String getStatusLine()
This property contains the first line of the last server response. This value can be used for diagnostic purposes. If an HTTP error is returned when calling a method of the bean, the error string is the same as the StatusLine property.
The HTTP protocol specifies the structure of the StatusLine as: [HTTP version] [Result Code] [Description].
public int getTimeout()
If the Timeout property is set to 0, all operations
will run uninterrupted until successful completion or an error condition
is encountered.
If Timeout is set to a positive value, the bean will
wait for the operation to complete before returning control.
The bean will use DoEvents to enter an efficient wait loop
during any potential waiting period, making sure that all system events
are processed immediately as they arrive. This ensures that the host
application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete,
the bean throws an exception.
Please note that by default, all timeouts are inactivity timeouts ,
i.e. the timeout period is extended by Timeout seconds when
any amount of data is successfully sent or received.
Optionally, the behavior of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum
of Timeout seconds since the beginning of the operation, without
extending the timeout period during communications.
This behavior is controlled by the ipworksssl.Https#config configuration setting.
The default value for the {@link ipworksssl.Https#getTimeout Timeout} property is 60 (seconds).

IPWorksSSLException
public java.lang.String config(java.lang.String configurationString)
throws IPWorksSSLException
{@link ipworksssl.Https#config Config} is a generic method available in every bean. It is used to set and retrieve {@link ipworksssl.Https#config configuration settingsfor the bean.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the {@link ipworksssl.Https#config Config} method.
To set a configuration setting named PROPERTY , you must call Config("PROPERTY=VALUE") , where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a {@link ipworksssl.Https#config configuration setting, you must call Config("PROPERTY") . The value will be returned as a string.
The bean accepts one or more of the following configuration settings . Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the {@link ipworksssl.Https#config Config} method.
The {@link ipworksssl.Https#getAuthScheme AuthScheme} property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".
Note that following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server and port are different than the existing one, {@link ipworksssl.Https#getUser User} and {@link ipworksssl.Https#getPassword Password} are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.
A {@link ipworksssl.HttpsRedirectEvent Redirect} event is fired for every URL the product is redirected to. In the case of automatic redirections, the {@link ipworksssl.HttpsRedirectEvent Redirect} event is a good place to set properties related to the new connection (e.g. new authentication parameters).
The default value is 0 (Never). In this case, redirects are never followed, and the bean throws an exception instead.
Valid options are:
NOTE: This functionality is only available in Java and .NET.
NOTE: This functionality is only available in Java and .NET.
Use this configuration option with caution. If this configuration option contains invalid headers, HTTP requests may fail.
This configuration option is useful for extending the functionality of the bean beyond what is provided.
NOTE: This is the same as Host . This setting is provided for use by beans that do not directly expose Firewall properties.
{@link ipworksssl.Https#getRemotePort RemotePort} is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the {@link ipworksssl.HttpsConnectionStatusEvent ConnectionStatus} event.
The connection to the firewall is made by calling the {@link ipworksssl.Https#connect Connect} method.
In the second scenario, {@link ipworksssl.Https#config is a positive value, the system will attempt to send pending data until the specified {@link ipworksssl.Https#config is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the bean returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
If the bean is connected, the {@link ipworksssl.Https#getLocalHost LocalHost} setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
{@link ipworksssl.Https#getLocalPort LocalPort} cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
If no {@link ipworksssl.Https#getEOL EOL} is found, and {@link ipworksssl.Https#config bytes are accumulated in the buffer, the {@link ipworksssl.HttpsDataInEvent DataIn} event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for {@link ipworksssl.Https#config is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 bytes.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the {@link ipworksssl.Https#config config setting.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the {@link ipworksssl.Https#config config setting.
TLS 1.1 and TLS1.2 support are only available starting with Windows 7.
The special value "*" (default) picks the default SSL provider defined in the system.
Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed.
The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Example values:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA"); Possible values include:
SSLEnabledCipherSuites is used together with SSLCipherStrength .
Note: This configuration setting is available only in .NET and Java.
obj.Config("SSLEnabledProtocols=3072"); // TLS1.2 (supports SHA_256)
obj.Config("SSLAlgorithmList=CALG_SHA_256;CALG_MD5"); Possible values include:
This option is only valid in Windows.

If LocalFile is not empty the data (not the headers) is written there as well.
If the goal is to upload a file or binary form data to a receiving script, the postdata must be MIME encoded, or you should use the WEBUPLOADS or WEBFORMS component.
Example (Performing a Post)
HTTPControl.ContentType = "application/x-www-form-urlencoded"
HTTPControl.PostData = "firstname=Tom&lastname=Thompson&country=US"
HTTPControl.Post(myurl)

public void resetHeaders()
throws IPWorksSSLException
LocalFile , and AttachedFile .
This method resets all the HTTP Headers as well as LocalFile and AttachedFile to "" (empty string). It also resets the Cookie collection
. Use this method before creating a new request, so that headers from the previous message are not carried over to the next one.
IPWorksSSLException
public void setDownloadStream(java.io.OutputStream downloadStream)
throws IPWorksSSLException
This method sets the stream to which the downloaded data from the server will be written. If a download stream is set before the Get method is called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.
The bean will automatically close this stream if ipworksssl.Https#config is true (default). If the stream is closed, you will need to call {@link ipworksssl.Https#setDownloadStream SetDownloadStream} again before calling {@link ipworksssl.Https#get Get} again.
The downloaded content will be written starting at the current position in the stream.
Note: {@link ipworksssl.Https#setDownloadStream SetDownloadStream} and {@link ipworksssl.Https#getLocalFile LocalFile} will reset the other.
IPWorksSSLException
public void setUploadStream(java.io.InputStream uploadStream)
