I'm trying to redirect any non-www prefixed traffic to the www prefixed domain. I'm using Umbraco as the CMS and have added the following code into the urlrewritingnet config file:
<add name="nonWWW"
virtualUrl="^(?!www\.)(.*)$"
rewriteUrlParameter="ExcludeFromClientQueryString"
destinationUrl="http://www.domain.co.uk$1"
ignoreCase="true" />
I'm getting a "is not a valid virtual path" error
