I have a registered domain name that I would like to use for my personal website e.g. www.mydomain.com. I have setup this domain to redirect to a different domain that is automatically updated with my IP address by my router. For this example the domain is called http://myname.someaccount.org.<BR><BR>My problem is that when I access my site using http://myname.someaccount.org I can login using form authentication. When I try and access it via www.mydomain.com, although the login page loads up, when I click my login button I am redirected back to the login page again with no error messages.<BR><BR>I am pretty certain my problem is to do with the host domain changing after the cookie using by form authentication has been created. What I don't know is what I need to do to try and get this working.<BR><BR>Has anyone any ideas?
