Sharing Authentication between ASP.NET sites
<p>I have two ASP.NET sites (they can not run in the same process) and I need to share authentication between them.  If a user is in site A already authenticated and then goes to site B, I need to have a way to share this information with site B so the user is not asked to authenticate again.  The same is true both ways.  How do you share this information?</p>
