Return the value of a request header for the
specified client session.
object.GetHeader( ClientId, HeaderName, HeaderValue )
- An integer that identifies the client session.
- A string that specifies the name of the header field. Header
names are not case-sensitive and should not include the colon which
acts as a delimiter that separates the header name from its value.
- A string variable that is passed by reference which will contain
the value of the header when the method returns.
A Boolean value that specifies if the method was successful.
The GetHeader method will return the value of a specific
header field included in the request sent by the client. Typically
this is used within an OnCommand event handler when the server
application needs to process a custom command. The GetAllHeaders
method can be used to obtain a copy of the complete request header
block submitted by the client.

headers that are used.
