The main idea behind writing this plugin is that, this should only be required/used on a need basis and only in the interim, while the legacy systems enhance to accept headers in any case. On the other hand, if we change the implementation to ALWAYS send camel case headers, that would be incompatible with HTTP2 (HTTP/2 mandates the sender to use lowercase headers (and the receiver to do a case-insensitive comparison) as well as inefficient, when not required, right? http://tools.ietf.org/html/draft-ietf-httpbis-http2-12#section-8.1.3 Just as in HTTP/1.x, header field names are strings of ASCII characters that are compared in a case-insensitive fashion.

James Peach commented on TS-2812:
-
AFAICT, this is an implementation issue with the in-core SPDY implementation.
It implements headers with {{FetchSM::ext_add_header}} which just writes the
raw header values. The original experimental SPDY implementation uses
{{TSMimeHdrFieldCreateNamed}} to create the HTTP request header, which I
believe converts well-known headers to their canonical case.

to handle lower case hdrs mandated by SPDY (and even http 1.0). This simple
plugin converts the lowercase header names into camel case and could be used
