We thought that this kind of rewrite can be achieved by the configuration
of the backend severs, but in some configuration, however, it may get
complicated. So we decided to implement at least location rewrite in
nghttpx.
This commit also contains a fix to the bug which prevents the http2
backend request from concatenating header fields with the same value.
This is pathological case, but we may get RST_STREAM to the promised
stream while we are sending PUSH_PROMISE. To handle this case,
instantiate Request object before transmission.
The option syntax is <PATH>=<PUSH_PATH,...>.
Push resources PUSH_PATHs when PATH is requested. This option can be used
repeatedly to specify multiple push configurations. For example,
-p/=/foo.png -p/doc=/bar.css
PATH and PUSH_PATHs are relative to document root.
This commit also changes SPDY's flow control size. Previously,
the size for SPDY is the same amount of bytes with HTTP/2.
For example, --frontend-http2-upstream-window-bits=N,
the window size is 2**N - 1. Now SPDY code uses 2**N.
Remove sorting headers from library code. The application must sort
them if necessary. nghttpx and nghttpd do the sorting of the headers
in stable way if names are equal.
nghttp2_session_client_new2 and nghttp2_session_server_new2 take
additional parameters which specifies session options.
nghttp2_set_option is somewhat crumsy because of type checking.
Now we use nghttp2_opt_set, which specifies individual options with
types. We changed the value of nghttp2_opt, so this change will
require re-compile.
Using --cacert to load certificate for client certificate authentication
is problematic since, --cacert is also used for client mode.
This commit adds --verify-client-cacert option which specify the CA
certficate file used only for client certificate validation.
This change also removes the default certficate load function for
client certificate validation.
