nginx 0.5.34
*) Change: now the full request line instead of URI only is written to
error_log.
*) Feature: Cygwin compatibility.
Thanks to Vladimir Kutakov.
*) Feature: the "merge_slashes" directive.
*) Feature: the "gzip_vary" directive.
*) Feature: the "server_tokens" directive.
*) Feature: the "access_log" directive may be used inside the
"limit_except" block.
*) Bugfix: if the $server_protocol was used in FastCGI parameters and a
request line length was near to the "client_header_buffer_size"
directive value, then nginx issued an alert "fastcgi: the request
record is too big".
*) Bugfix: if a plain text HTTP/0.9 version request was made to HTTPS
server, then nginx returned usual response.
*) Bugfix: URL double escaping in a redirect of the "msie_refresh"
directive; bug appeared in 0.5.28.
*) Bugfix: a segmentation fault might occur in worker process if
subrequests were used.
*) Bugfix: the big responses may be transferred truncated if SSL and
gzip were used.
*) Bugfix: compatibility with mget.
*) Bugfix: nginx did not unescape URI in the "include" SSI command.
*) Bugfix: the segmentation fault was occurred on start or while
reconfiguration if variable was used in the "charset" or
"source_charset" directives.
*) Bugfix: nginx returned the 400 response on requests like
"GET http://www.domain.com HTTP/1.0".
Thanks to James Oakley.
*) Bugfix: a segmentation fault occurred in worker process if
$date_local and $date_gmt were used outside the
ngx_http_ssi_filter_module.
*) Bugfix: a segmentation fault might occur in worker process if debug
log was enabled.
Thanks to Andrei Nigmatulin.
*) Bugfix: ngx_http_memcached_module did not set
$upstream_response_time.
Thanks to Maxim Dounin.
*) Bugfix: a worker process may got caught in an endless loop, if the
memcached was used.
