Catch my Point

I remember when I first started playing with DNN about 3 years ago, it was such a pain to make DNN WebSite work on a not standard Port number (other than 80), because of this reason I always used host headers for DNN development Env. (Windows 2k3 Server).

The problem is when you change the Portal Alias and add a port, and try to access the portal you will have a never ending loop of redirection

If you use Internet Explorer (any version) : you will see your worker process takes 100% CPU and take up all memory and recycles itself.If you use Firefox : it show a below friendly message

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

* This problem can sometimes be caused by disabling or refusing to acceptcookies.

Solution :Simple add below element to your web.config (within <appSettings>)

<add key="UsePortNumber" value="True"></add>
