What is the URL_CHANGED Event on IIS7 Request Tracing Log?

Question

Hi,

I just enabled Failed Request Tracing for a site and I get a URL_CHANGED event as the third item on the log.

1. GENERAL_REQUEST_START SiteId="1", AppPoolId="DefaultAppPool", ConnId="1610613013", RawConnId="0", RequestURL="http://example.com:80/test/wp-admin/", RequestVerb="GET" 15:35:54.176 
2. GENERAL_SET_REQUEST_HEADER HeaderName="AspFilterSessionId", HeaderValue="", Replace="true" 15:35:54.192 
3. URL_CHANGED OldUrl="/test/wp-admin/", NewUrl="/index.php/test/wp-admin/" 15:35:54.192

Can someone tell me where the URL_CHANGED event comes from and how I can prevent it?

I'd say this might be a question for the stackoverflow sister site serverfault.com

This happened to me yesterday. In the end, when I enabled Failed Request Tracing logs for all areas in IIS, I could see that it was actually being changed in an ISAPI filter.
