nginx 1.1.6 *) Change in internal API: now module context data are cleared while internal redirect to named location. Requested by Yichun Zhang. *) Change: if a server in an upstream failed, only one request will be sent to it after fail_timeout; the server will be considered alive if it will successfully respond to the request. *) Change: now the 0x7F-0x1F characters are escaped as \xXX in an access_log. *) Feature: "proxy/fastcgi/scgi/uwsgi_ignore_headers" directives support the following additional values: X-Accel-Limit-Rate, X-Accel-Buffering, X-Accel-Charset. *) Feature: decrease of memory consumption if SSL is used. *) Bugfix: some UTF-8 characters were processed incorrectly. Thanks to Alexey Kuts. *) Bugfix: the ngx_http_rewrite_module directives specified at "server" level were executed twice if no matching locations were defined. *) Bugfix: a socket leak might occurred if "aio sendfile" was used. *) Bugfix: connections with fast clients might be closed after send_timeout if file AIO was used. *) Bugfix: in the ngx_http_autoindex_module. *) Bugfix: the module ngx_http_mp4_module did not support seeking on 32-bit platforms.
