I upgraded my website from Umbraco 4.19 to Umbraco 4.10.0 based on the official direction. I modified the web.config and other files in the /config folder as directed.

However, I found the UrlRewriting doesn’t work in the upgraded website. The code of UrlRewriting.config is as follows:

<urlrewritingnet rewriteOnlyVirtualUrls="true"

    contextItemsPrefix="QueryString"

    defaultProvider="RegEx"

    xmlns="http://www.urlrewriting.net/schemas/config/2006/07">

    <rewrites>

        <add name="TextPage"

           virtualUrl="~/(.*?)/(\d{1,3})/"

           rewriteUrlParameter="ExcludeFromClientQueryString"

           destinationUrl="~/$1.aspx?page=$2"

           ignoreCase="true" />

        <add name="TagList"

           virtualUrl="~/(\S+)-tags/"

           rewriteUrlParameter="ExcludeFromClientQueryString"

           destinationUrl="~/tags.aspx?tag=$1"

           ignoreCase="true" />

    </rewrites>

</urlrewritingnet>

I cannot found any solution for it because I don’t know how the UrlRewriting works. Could anybody tell me how I can solve the problem? Thanks.
