The problem with this solution is that it only looks at one type.

cfg->types is a list of all enabled mime_types. In 4.0 > only the URI  
is looked at. In 3.0 < It was a combination of URI and mime type. The  
reason I took this out in 4.0 was that mime type was not always set  
at the proper stage of execution (and if it wasn't then we ended up  
with a problem where more mime types had to be added/debugged).

I've not had a chance to test the solution I posted. When I do, or  
when someone else confirms, I'll whip up a test binary for anyone who  
wants to try it out.
