title: Asp.net forms authentication IIS 7.5 with multiple servers
body: <p>I have a Asp.Net web application running on Windows 2008 R2 (IIS 7.5). I have two servers WWW1 and WWW2 and the DNS records are set up for round robin DNS for "www". I increased the AppPool timeout and the Session State timeout settings so users don't get logged out after 20 minutes. However I've noticed users are getting logged out randomly. I think what is happening is the user goes to www.foo.com and logs in and then afterward some time the round robin navigates them to the opposite server in the cluster (WWW1 or WWW2) where the cookie was not created and therefore prompts them for a login.</p>
  
  <p>How can I get this to work and still keep my high availability solution using round robin DNS? </p>
