nginx 0.7.11 *) Change: now ngx_http_charset_module does not work by default with text/css MIME type. *) Feature: now nginx returns the 405 status code for POST method requesting a static file only if the file exists. *) Feature: the "proxy_ssl_session_reuse" directive. *) Bugfix: a "proxy_pass" directive without URI part might use original request after the "X-Accel-Redirect" redirection was used; *) Bugfix: if a directory has search only rights and the first index file was absent, then nginx returned the 500 status code. *) Bugfix: in inclusive locations; the bugs had appeared in 0.7.1.
