I noticed that it's currently impossible to use mod_proxy_http2 in
conjunction with mod_rewrite's [P] request proxying:
RewriteEngine On
RewriteRule ^/foo h2c://hostname/bar [P]
mod_proxy_http2 registers on h2:// and h2c:// proxy URLs [1], however,
mod_rewrite needs an update to handle these as absolute URIs. Without
that, the configuration above is going to produce incorrectly rewritten
rewritten URLs, e.g.:
http://www.example.org/h2c://hostname/bar
I attached the patch with a fix for this issue. The second patch adds
the corresponding tests to the mod_http2 testing framework.
