Request Method Using Mixed case letters.

[sanjay9999]

Thanks for the update.
I have already taken care to hide the "nginx".

With CAPITAL letters, my testcase using "POSTSSS" for request_method, works
fine.However, for mixed-case and small-case , nginx default rule applies and
control does not reach my server block. hence I end up getting 400 error
with "nginx" server name in html response.
