Proper backtracking after space in a request line.

Upstream: cache revalidation with conditional requests.

2013-11-18T16:48:22+00:00

The following new directives are introduced: proxy_cache_revalidate,
fastcgi_cache_revalidate, scgi_cache_revalidate, uwsgi_cache_revalidate.
Default is off.  When set to on, they enable cache revalidation using
conditional requests with If-Modified-Since for expired cache items.

As of now, no attempts are made to merge headers given in a 304 response
during cache revalidation with headers previously stored in a cache item.
Headers in a 304 response are only used to calculate new validity time
of a cache item.

SPDY: fixed request hang with the auth request module.

2013-11-11T14:49:35+00:00

We should just call post_handler() when subrequest wants to read body, like
it happens for HTTP since rev. f458156fd46a.  An attempt to init request body
for subrequests results in hang if the body was not already read.

Configure: call "make distclean" for libatomic.

Win32: plugged memory leak.

Gunzip: proper error handling on gunzipping an empty response.

2013-10-31T00:16:20+00:00

With previous code, an empty (malformed) response resulted in a request
finalized without sending anything to a client.

Gunzip: "error" logging level on inflate() errors.

2013-10-31T00:12:53+00:00

Errors can easily happen due to broken upstream responses, there is no
need to log them at "alert" level.

Removed extra allocation for $sent_http_last_modified.

2013-10-31T00:02:59+00:00

There is no need to allocate memory for "Last-Modified: " string,
the variable only contains date itself.
