Visual Studio .NET - Error with url rewritting

Asked By Nagaraj muthuchamy on 25-Mar-08 05:28 AM

I have implemented url rewriting for my site.
Its working well most of the time. but some times, It returns the 404 error.
then I refresh the page and it loads the correct page.

Environment: VS 2005,IIS 6,VB.NET,SQL Server

Thank you

HTTP 404 - SP replied to Nagaraj muthuchamy on 25-Mar-08 06:25 AM

If you view the IIS logs for the Web site, you see that the 404 error is returned after the HTTP GET request is redirected to the Exchange/USA/Username folder. The USA folder is only used in Exchange Server 5.5, and it does not exist in Exchange 2000.

This behavior can occur if Exchange 2000 Setup did not remove the existing Exchange Server 5.5 version of the Exchfilt.dll file from the list of ISAPI filters that are loaded by the default Web site. The old Exchange Server 5.5 Exchfilt.dll file automatically tries to redirect the user to the USA folder.

Thanks Sanjay,

We are not using Exchange Server and Exchfilt.dll is not added in ISAPI filter.

Here is the sample Error Log;
