Plesk 9.3.0 API RPC XML Response Problem

[RhysL]

I am able to submit an XML packet to the control agent seemingly correctly, I notice in the admin GUI that a session is created, so it appears to be accepting the packet correctly.

However, I am unable to determine anything further because the HTTP response packet is the default HTML login page. The only time I am able to receive anything different is if I submit an empty packet (no headers or anything) which returns an (expected) error XML packet (1003 Wrong request).

I have only found one other post regarding the same issue which was posted way back in 2007. It was resolved by upgrading the entire Plesk panel software. However the project I am doing is for a client, and I am unable to do use that resolution.

Plesk Panel 9.3.0
OS: Microsoft Windows 5.2
Platform: VB.NET

After upgrading to Plesk 9.5.4 I still had the same problem. However I did find the solution, as posted in this thread http://forum.parallels.com/showthread.php?p=435185
