Hi.
Single sign on between several web servers is actually a complex issue, but one thing you could try in you asp.net app, is to write a cookie to the client when the session is established, and check for the existents of this client cookie in the start of each request (global.asax Begin_Request), and (if you donââ¬â¢t have a session), recreate the session based on the client cookie. This method, of course requires that you maintain the session data somewhere.

You can also check out this article (If you can use LDAP):

A book is claming to have the solution (I have not read it):

A google search on: single sign on "Asp.net" coldfusion
Gives you quiet a few pointers
