I have a nice little file upload control I wrote for ASP.NET webforms that utilizes an IFrame and ASP.NET AJAX.

However, on large uploads, the browser times out before it can finish posting the form.

Is there a way I can increase this?

I'm not really interesting in alternative solutions, so don't suggest changing the entire thing out please. It works good for <5 meg uploads, I'd just like to get it up to about 8mb.

EDIT: Setting the timeout in Page\_Load didn't appear to change anything.
