Why ExecuteURL doesn't work in webconfig? [closed]

I used this code in to web.config in plesk.

<httpErrors errorMode="Custom" existingResponse="Auto">
 <remove statusCode="404" subStatusCode="-1" />
 <error statusCode="404" subStatusCode="-1" prefixLanguageFilePath="" path="/url.asp"  responseMode="ExecuteURL" />
</httpErrors> 

But pages did not redirect to URL.asp! I use this method to make URL friendly in classic ASP. It worked fine in other servers but I have issue in current server.

This is the plesk log:
