Capturing infor from asp for authentication

[raamsbw]

Dear Friends
In our web server we have two applications 1.ASP and 2.PHP.

Now the requirement is ,Once the user logged in successfully with ASP application ( it's main one )and if they want to login to PHP application from the link provided in the ASP application ,the PHP system captures the login information and allowed them to avail the PHP application upon successful authenticationi.e (i.e iwith out loggin in to PHP application).

Note.The PHP system uses MySQL as a DB.

Thanks in advance.
