IIS MODULE_SET_RESPONSE_ERROR_STATUS

Question

Im getting 404 error on my web application, I also try doloto : http://research.microsoft.com/en-us/projects/doloto/ , but reports tell me is an compression issue, I dont think so cause is just one page with some ajaxcontroltoolkit features.

this is the stack :

There's something wrong in your web.config, a path to a request handler is not right. Verify all of the path information is correct in the <httpHandlers> section of your web.config. Here's an MSDN article that discusses registering HTTP handlers.
