问题
Scenario: I am trying to develop a web site which features a chat widget. I am using ASP.NET, C#, agsXMPP library as my tools in achieving this purpose. I use Openfire jabber server for XMPP server.
Problem: When I access the widget on the website and start chatting, I send a message with message type "chat" and thread set. I receive this message on the client in this case Spark. When I reply to this message, I see that the thread value is not the same as the one I sent? According to RFC 3921 section 2.1.2.3, The value of the element is generated by the sender and SHOULD be copied back in any replies. However, I don't see this happening.This means, I cannot link the response with the message I sent.
Can anyone help me with what I am missing? The following is the message sent and received.

The RFC says the "thread" element SHOULD (see http://tools.ietf.org/html/rfc2119) be returned in replies. It may be that this client just didn't implement it.
