title: Maintaining session state inside an iFrame
body: <p>not sure if I'm going crazy, but I am having issues with session state inside an iFrame. Its a simple setup of one domain inside another. I dont need to share anything across the domains, all I want to do is embed a website inside another website and I want that embedded site to be able to log in / edit / update / etc using cookies / session state.</p>
  
  <p>To remove all the complexities of server farms / shared sql session state etc, I created a simple html page served up by IIS that simply has an iFrame tag inside of it that call my site. All loads and is great, but the moment I try and log in, I get stuck in an endless loop of log in screens as the session is re-created with each request and I get logged out etc...</p>
  
  <p>What am I missing? was there some uber browser security upgrade that cam into effect recently? </p>
  
  <p>Any guidance would be awesome.</p>
  
  <p>PS. I've got the p3p headers in place</p>
