Question

Wildcard subdomain cookies sessions possible?

Asked by: bemara57

I'm having a problem with sessions persisting via cookies going from standard http to https SSL mode. The problem is that my website gets surfed with http://www.mydomain.com. But then when going into SSL mode, my website becomes https://secure.mydomain.com. Because of the change of subdomain, the session gets completely lost from that point on. Is there a way the .NET framework can handle wildcard subdomain cookies for sessions?? The only alternatives I see is to get a wildcard SSL certificate which is 10 times the price, or the ugly session ID in the URL. I'm hoping .NET cookie sessions can understand the concept of wildcard subdomains.

Try setting the domain for your cookies to "mydomain.com".  When the browser receives a cookie set for "mydomain.com", it will subsequently include that cookie in requests send to any *.mydomain.com domain.

In the .NET framework, you can set a given cookie's domain by setting the System.Net.Cookie instance's Domain property.  See http://msdn2.microsoft.com/en-us/library/ms178194(VS.80).aspx and http://msdn2.microsoft.com/en-us/library/system.net.cookie.domain(VS.80).aspx for info and examples.
