I'm not sure of the description to write there, so I just mention it in the doc and hope s.o. will find the words :)

And the socache provider interface for Redis


And provide some nice usage stats. Could be prettier, for sure.

Needs LOGNO #s

reorganize mod_socache_redis so it compiles w/o apr-redis

It looks like this was the original intent. The provider
is not registered if apr-redis is missing.

It was previously failing to compile due to the dirconf being
hidden behind the #ifdef guard but not the routine module
code that used it.




Fix some HTML tags

Couls also be <br> or <br/> but some (very) old clients don't like it.
httpd is not really consistent on it. (personnlaly <br> would be just fine for me but <br /> is the most commonly used form)

related to http://svn.apache.org/viewvc?view=revision&revision=1774602


Use apr_pcalloc in the 'create' function. All the fields are initialized in the 'init' function, but it is It is cleaner and more future proof.

Small style correction (remove extra spaces)

  *) mod_http2: when SSL renegotiation is inhibited and a 403 ErrorDocument is
     in play, the proper HTTP/2 stream reset did not trigger with H2_ERR_HTTP_1_1_REQUIRED.
     Fixed. [Michael Kaufmann] 

  *) mod_http2: new configuration directive: `H2Padding numbits` to control 
     padding of HTTP/2 payload frames. 'numbits' is a number from 0-8,
     controlling the range of padding bytes added to a frame. The actual number
     added is chosen randomly per frame. This applies to HEADERS, DATA and PUSH_PROMISE
     frames equally. The default continues to be 0, e.g. no padding. [Stefan Eissing] 
  
  *) mod_http2: ripping out all the h2_req_engine internal features now that mod_proxy_http2
     has no more need for it. Optional functions are still declared but no longer implemented.
     While previous mod_proxy_http2 will work with this, it is recommeneded to run the matching
     versions of both modules. [Stefan Eissing]
  
  *) mod_proxy_http2: changed mod_proxy_http2 implementation and fixed several bugs which
     resolve PR63170. The proxy module does now a single h2 request on the (reused)
     connection and returns. [Stefan Eissing]
  
  *) mod_http2/mod_proxy_http2: proxy_http2 checks correct master connection aborted status 
     to trigger immediate shutdown of backend connections. This is now always signalled
     by mod_http2 when the the session is being released. 
     proxy_http2 now only sends a PING frame to the backend when there is not already one
     in flight. [Stefan Eissing]

  *) mod_proxy_http2: fixed an issue where a proxy_http2 handler entered an infinite 
     loop when encountering certain errors on the backend connection. 
     See <https://bz.apache.org/bugzilla/show_bug.cgi?id=63170>. [Stefan Eissing]

  *) mod_http2: Configuration directives H2Push and H2Upgrade can now be specified per 
     Location/Directory, e.g. disabling PUSH for a specific set of resources. [Stefan Eissing]

  *) mod_http2: HEAD requests to some module such as mod_cgid caused the stream to
     terminate improperly and cause a HTTP/2 PROTOCOL_ERROR. 
     Fixes <https://github.com/icing/mod_h2/issues/167>. [Michael Kaufmann]
