Detect a software installed on the client machine

[Raj]

Hi,
I want to detect a s/w installed on the browser client machine and
change my asp.net application's behavior according to that. I already
have the javascript to detect the s/w installed on the machine. Can
someone guide me as to how I should pass this onto the asp.net web
server.

TIA
Raj

If you already have a script that detects this, you could put this script on
your front page, pass it in via a hidden form field, and then store this in
a session variable.
