I have an http handler in an ashx file in the root directory of my application.  This handler formats RSS for a podcast.  But I am having trouble with a recent update to this (was working fine, before).

When I navigate to the podcast here: http://imcwbeta.org/tara.ashx it redirects me here: http://imcwbeta.org/vulnerabilityPatchError.aspx?aspxerrorpath=/tara.ashx and logs the following error:

But it looks like the ashx isn't even called.  What could be causing this?

Thanks!

Thanks, I will look into this. This one is still baffling me.
