detect a session cookieless fr. ASP

[Anon]

How recently, there is 2 seperate machine, under a same domain(mydomain.com).

Machine A is runnging ASP, and Machine B is running PHP.

I am wondering how can i detect the session well which create from the .asp from machine B to A?

let said i create a cookie named 'username' at ASP machine, so i can straight away echo it out in PHP machine like this <? echo $username ?> ???

Thanks
Louis
