Fellow Sajha friends
 
I am in the process of developing Facebook apps for client(s) that runs on iFrame. Since last October, Facebook requires a secure connection to run app. Not sure how to handle this situation as our entire clients website run on same server.  

This app will be used by only few clients. I did some Google about the SSL certificate types. Looks like multi-domain Certificate might work (Not sure though).  What kind of setup is required on Load balancer? And also I think I need to reconfigure the IIS on webserver to support secure request.  Please suggest.

There is a single website setup on IIS. Based on the URL requested, the code pulls the settings from the database and displays website. For example, if the request is domain1.com, the code will pull only setting for domain1 and displays the content on domain1.com. If the request URL is domain2.com, it pulls the setting only for domain2 and displays the content on domain2.com

domain1.com/ social/facebookapp

domain2.com/social/facebookapp

Any suggestions will be highly appreciated. 

Thank you
