It took me a whole week to get a WWWC app up and running on IIS 7.5. The learning curve was about 80% grade, a heavy climb. At least the configuration isn't scattered around the registry. The IIS 7.5's habit of reacting to some changes immediately and to others with a considerable delay didn't help at all (it's still redirecting immediately to my first scripted page, disregarding the edits of index.html I did two days ago).
Now I got it more or less working, except that for any .js or .css file that's linked inside the page I keep getting nothing - they are not loaded. Firebug shows that the response for each is an error page, something about handler being "not yet determined", error code 0x80070002 and "The resource you are looking for does not have a handler associated with it".
Both .js and .css are recognized MIME types, neatly listed in ApplicationHost.config - do I have to list them in my app's web.config too? That would mean that the inheritance is broken, but wouldn't be a first. I already saw instructions like "must be registered in both xxx and yyy sections for this to work".
