 Re: Web Response sent to wrong Client
Your absolutely correct:
I was trying to find the solution to this problem in the Code behind (C# code). I stumbled on another discussion which indicated that the default response of programmers is to look at the code, not the xml.
First suspecting the session ID was not being honoured I changed the configuration to display the Session ID in the query string. This indicated that the Session ID was being honoured. I then started to work through the XML attributes, and when checking the documentation of the OutputCache directive thougth that caching on the server side (which is what this does, apparently) would not be a good thing if two users hit the server concurrently.
I removed the line indicated below and the problem disappeared.
Possible implications of removing this tag: unknown - maybe it will only mean the application works. If it breaks again I will post here.
What interested me most, is this code was autogenerated. I did not put it there (I had no idea what it did) so it was never on my radar.
Cheers
Wee!
