Could not load type 'ProtocolSupportModule'

Question

I've found a boss-level error that forced me to become an active member of stackoverflow.

I am hosting an MVC app and on root level it works, however css and images are failing. Even when going to the image directly via URL I get the following error:

Could not load type 'ProtocolSupportModule'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: Could not load type 'ProtocolSupportModule'.

Okay so I figured this out. Under handler mappings, the OptionsVerbHandler was set to allow all verbs under the request restrictions section. I set it to only allow the OPTIONS verb and created extra handlers for POST and GET.

UPDATE:

WHEN a GETHandler is specified on a folder with stylesheets or images the ProtocolSupportModule error occurs when the image/stylesheet is called. When no Gethandler is present on dll's views, the MVC app displays a verb rights error. I got around this by setting the handlers on folder level. This is a bad way of doing it. Are there any better ideas? I am sure the MVC framework should handle this automatically?
