Subject: [ruby-core:69670] [Ruby trunk - Bug #11285] [Open] Net::HTTP should handle content-coding with case-insensitive

Issue #11285 has been reported by Andy Chu.

----------------------------------------
Bug #11285: Net::HTTP should handle content-coding with case-insensitive 
https://bugs.ruby-lang.org/issues/11285

----------------------------------------
When Ruby Net::HTTP sent a request. It by default set the content to be compress with header: Accept-Encoding

But if server return with content-encoding = GZIP (or any case other then all lower case) it will not tread the body as compressed.

According to HTTP 1.1 spec, Content-Encoding should be value used by content-coding, and the value of content-coding should be case-insensitive
content-coding: http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.5

I think simply change the code here: https://github.com/ruby/ruby/blob/trunk/lib/net/http/response.rb#L253

from

case self['content-encoding']

to 

case self['content-encoding'].downcase

should work
