HTTP message format

An HTTP message contains components that are appropriate to its type.

The bit stream containing headers and body is parsed and represented within the message tree when an input request is received by an HTTPInput node, or when a response from a web service is received by the HTTPRequest node. A bit stream is created by parsers from the appropriate parts of the message tree when a reply is sent to the client by the HTTPReply node, or when a message is sent by the HTTPRequest node. For further details about these actions, see the individual node descriptions.
