nginx 0.7.44 *) Feature: the ngx_http_proxy_module preliminary cache support. *) Feature: the --with-pcre option in the configure. *) Feature: the "try_files" directive is now allowed on the server block level. *) Bugfix: the "try_files" directive handled incorrectly a query string in a fallback parameter. *) Bugfix: the "try_files" directive might test incorrectly directories. *) Bugfix: if there is the single server for given address:port pair, then captures in regular expressions in a "server_name" directive did not work.
