POST request static File response 405

Using the Post method to request a static file such as JS, HTML the General Web server will return 405 Method not allowed.

I test the Web server with IIS (WINDOWS10+IIS10), in theory, get method can request, the Post method should also be able to do not take care of these Web servers to do such a default setting, I just want to implement the Post method of successful completion of the request.

Searched a lot of articles, maybe I have no essentials, has not been successful. After noticing the error description and recommendations of IIS, the following adjustments have been made, resulting in success.

Handler mappings > Staticfile > Request throttling > Set Mappings ( be sure to uncheck) > Set predicates (Select all verbs or add post to the predicate).
