I've recently upgraded my site from DNN5x to 6.1.3 (iis7).  Since the upgrade I noticed that when I log in using a URL like www.mysite.com then  then navigate to a url like mysite.com (without the www), i am n longer logged in.

Also, the URL's from the menu structure sometimes point to the www url and other times dont. I havnt quite figured out the pattern here.  Anyway, I dont have much experience with the admin & config side of DNN  but my hosting provider has asked me to add the following lines to the web.config file just beneath the  </handlers>  in the <system.webServer> node.

<rewrite>
<rules>
<clear />
<rule name="WWW Rewrite" enabled="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" negate="true"
pattern="^www\.([.a-zA-Z0-9]+)$" />
</conditions>
<action type="Redirect" url="http://www.{HTTP_HOST}/{R:0}"
appendQueryString="true" redirectType="Permanent" />
</rule>
</rules>
</rewrite>

This didnt work & I just kept getting a config error like this..

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

anyone have any sugestions.

Cheers
