Keeping user session info across multiple domains

[Guest]

Hello

I was wondering if there was a way to keep a user's session info across multple domains
For example, company A owns website www.a.com and www.b.com. A user logs into www.a.co
and later visits www.b.com. I would like to have it where the user doesn't have to login again.

Thank
Le

Le,

You might try using a SQL database for session variables rather than the
built-in session object in ASP.NET.

I agree with Brandon.
You can also try to use the ASP State Service.
Generally speaking, cross domain session sharing is security-hazard, unless
you can make sure that these different urls domains belong to the same
application domain from the perspective of the web servers that manage them.
