IIS does not respond to <error statusCode="404" redirect="~/Errors/Error404.aspx" />.  Other errors do. Why?

The system.web part of my web.config file has the following :

            <customErrors defaultRedirect="~/Errors/GeneralError.html" mode="On">
                  <error statusCode="404" redirect="~/Errors/Error404.aspx" />
                  <error statusCode="403" redirect="~/Errors/Error403.aspx" />
            </customErrors>

The error 403 page is correctly called when I try to access, for example the web.config file with the browser. However, I cannot get the dyamic 404 page to be called - the IIS default is called instead.

Can anyone explain what on earth is going wrong? It looks so simple in principle!

In my application, the 404 custom error must be configured from the web.config file. A direct change to the IIS would otherwise do the job, but this is not an option.

Thanks.

Ok, the answer to this question is that unless the requested URL ends in ".aspx", the 404 error will not be handled by the application. When it ends in ".aspx", IIS calls the designated page with the URL argument "aspxerrorpath=<filename>.aspx".

If you want to avoid this ugly URL, or extend the error handling beyond aspx pages, then you have to speak nicely with your site hosting company and ask them to change the configuration of IIS to call a particular URL when error 404 is generated.

Personally, I think the dynamic 404 error handling could have been better implemented.

As I have answered my own question, I'd like to close this now and have my points refunded.

Thanks.
