Bug: Custom headers modified to lower case

[jindraf]

Custom headers names are modified to lower case by RESTED plugin. For instance, if I set "Authorization" text as a key of header, the server receives "authorization" (checked in browser devel tools). Servers strictly requesting "Authorization" are than failing with deny access.

Accept: /
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
authorization: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
test: xxxxxxx
DNT: 1
Connection: keep-alive
Cookie: PHPSESSID=xxxxxxxxxxxxxxxxxxxxxx
Sec-Fetch-Dest: empty
Sec-Fetch-Mode: cors
Sec-Fetch-Site: same-origin
Pragma: no-cache
Cache-Control: no-cache

Header names are case-insensitive. Modification may be done both by browser or server you should never rely on the case.

Clear. Ok, this isn't a bug. Anyway. It is not cool that the plugin is changing the case. I see it as unexpected behavior. The result is that users cannot use RESTED client with not strictly correct servers. User/client without direct access to the server (to fix it), has to look for another plugin to use.
