Virtual Directory and ASP.NET AJAX

I have setup a virtual directory in one of my websites but the updatepanels are not taking effect, they are still reposting the whole page. The pro开发者_StackOverflowblem seems to be the virtual directory because I tried setting it up as a website instead and the updatepanels worked... but when I set it back as a virtual directory they do not work anymore.

Any ideas?

Thank you!

Have you tried this:

Its a known problem that will cause AJAX to not work.
