Yes, that's what I have done in the past. The HTTP server is related to the 'published applications' function within Citrix. If you take a Citrix ICA client and attempt to list the published apps on a specified server you will see an HTTP POST request go to the Citrix HTTP server, I don't remember the script name but it is in a /scripts/ directory. Set up your Citrix connection, from the client, as a TCP/IP+HTTP connection and you will be able to examine the requests (which are cleartext) cheers Greg > -----Original Message----- > From: Erlend J.
