why is it, that On file upload, the Application_BeginRequest is not being triggered on published site?

Question

Hi,

I think part of the question is of course, how do I fix this:

I have an ASP.NET MVC site which on the web development environment Cassini triggers the:

protected void Application_BeginRequest(object sender, EventArgs e) { }

on a file upload, but when I publish this to my IIS7 machine it will not trigger this any more..

It still gets called on any other normal page load, just uploads it isn't

Isapi seems to be what I need to get my hands on, because the request is probably not being handled by MVC on the published site, what can I do to make it so?

Would be nice if I could just tweak my RegisterRouters instead of changing the IIS configuration, but any hint in the right direction is appreciated!

Thank you,

Ric
