to fetch xml data from a link?

Hi all,
I'm using a hotlink for my application which will communicate with client application.
In the hotlink there are various parameters (protocol, webstore address, shipmenxmlurl,postbackurl,orderid,sec id). the protocol i m using can accept only 2048 bytes of data. but when when i m clicking on the hotlink, it returns error saying "could not load xml data".

The problem is i'm unable to see the xml data being sent through the hotlink to client application.
can anyone help me?
Thanks!

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...
