When I uploaded the site to the server, I got an HTTP Error 500.19 - Internal Server Error which says "Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'RewriteModule'". Error was in the following line in web.config
I got the solution to change the application config file from the following link:
http://support.microsoft.com/kb/942055
But, hosting providers won't allow that on server.
I added the following under where the RewriteModule is added
Also, there were some virtual directory issues. Hosting provider
changed that. Now it is working.
