What are you asking for help on? If you want to see the actual data going across the wire for testing purposes, use a sniffer (wireshark), a proxy tool (ie, Fiddler), or something like Firebug. If you're asking for help on troubleshooting the problem in general, we need to know a lot more about the setup - ie, what browser / client app, what server, what language, what is it suppose to do, etc...
