I am having some issues with replying to comments on review page. It is giving 500 error hence posting replies here.

@berker.peksag: Thanks! I will add the methods' documentation & examples into the Doc/library/http.server.rst. As well as include a few unit tests.

I searched through github and there doesn't seem to be many examples of "BaseHTTPRequestHandler copyfile". Still if you feel it is better not to make this change, I will revert it back.

I have submitted the contribuer-form on the same day as I submitted this patch. Waiting for it to be accepted.

Thanks again.
