This might help throughput, but it interfere stream priority. The
throughput issue is generally caused by the small buffer size to store
response body, which was 16K. We increased it to 128K to compensate
this change.
RFC 7540 says that proxy should not emit :authority when translating
HTTP/1 request in origin or asterisk form to HTTP/2. To keep this
semantics in tact, we should also refrain from emitting :authority if
it is missing (host header field is required in this case).
For HTTP/2, we do this validation in libnghttp2. http-parser does
this partially, when it parses URI, but it does not do anything for
Host header field. libspdylay does not perform anything. So do some
additional validation for HTTP/1 and SPDY cases. integration tests
were also added to make sure they work.
Header field related functions are now gathered into FieldStore class.
This commit only handles request. Subsequent commit will do the same
thing for response.
This commits enables HTTP/2 server push from HTTP/2 backend to be
relayed to HTTP/2 frontend. To use this feature, --http2-bridge or
--client is required. Server push via Link header field contiues to
work.
This change is required to show path attribute to mruby script. It is
desirable to construct URI from parts. Just checking method and path
is "*" is awkward.
To achieve host-path backend routing, we changed behaviour of
--backend-http2-connections-per-worker. It now sets the number of
HTTP/2 physical connections per pattern group if pattern is used in -b
option.
Fixes GH-292
There are many requests which changes its meaning when we rewrite
path. This is due to bad percent-encoding in URI; reserved characters
are just used without percent encoding. It seems this is common in ad
services, but I suspect more to come. For reverse proxying situation,
sane service most likely encodes URI properly, so probably this is not
an issue.
-b option syntax is now <HOST>,<PORT>[;<PATTERN>[:...]]. The optional
<PATTERN>s specify the request host and path it is used for. The
<PATTERN> can contain path, host + path or host. The matching rule is
closely designed to ServeMux in Go programming language.
This commit makes sure that WebSocket upgrade works for HTTP/1.1
frontend and backend pair. Actually, this implementation probably
supports other upgrade as well, other than HTTP/2 Upgrade, which is
handled specially in other place.
