Hi,
I have two applications with a single domain name (www.domain.com and test.domain.com). First one has been developed in .NET 2 and the other one with .NET 4.
I have configured web.config as these steps:
1- I've set the same machine key for both of them.
2- I've set the coockie name.
3- I've set the domain name to "domain.com".
4- Also, I've set hardcoded coockie domain name to "domain.com" .
Everything was working fine when both of them were running on a single web server. Recently, I've been asked to move test.domain.com to another server. After moving, authentication ticket is not valid on the second server.
I tested both of them on a single server again and everything was workinh fine, but in two servers users can't acces to test.domain.com. (Authentication Ticket is invalid)
Edited: The second server is a virtual (VMWare) server. I don't have any problem in physical servers. Go to the complete details ...
