Recently developed a aps.net Web site in two times, after deploying the Web site to IIS, enter: http://localhost/upload/error "http errors 500.0-internal Servererror",

HTTP Error 500.0-internal server errorinternal Server error Detailed error information

After some toss, know with the program rewrite URL module, but the problem is still unresolved, Kung fu is not a conscientious, found the reason:

The program has its own HttpModule URL rewrite module, and IIS has its own rewrite module, which is caused by conflicts.
