nginx-0.1.25-RELEASE import

    *) Bugfix: nginx did run on Linux parisc.

    *) Feature: nginx now does not start under FreeBSD if the sysctl
       kern.ipc.somaxconn value is too big.

    *) Bugfix: if a request was internally redirected by the
       ngx_http_index_module module to the ngx_http_proxy_module or
       ngx_http_fastcgi_module modules, then the index file was not closed
       after request completion.

    *) Feature: the "proxy_pass" can be used in location with regular
       expression.

    *) Feature: the ngx_http_rewrite_filter_module module supports the
       condition like "if ($HTTP_USER_AGENT ~ MSIE)".

    *) Bugfix: nginx started too slow if the large number of addresses and
       text values were used in the "geo" directive.

    *) Change: a variable name must be declared as "$name" in the "geo"
       directive. The previous variant without "$" is still supported, but
       will be removed soon.

    *) Feature: the "%{VARIABLE}v" logging parameter.

    *) Feature: the "set $name value" directive.

    *) Bugfix: gcc 4.0 compatibility.

    *) Feature: the --with-openssl-opt=OPTIONS autoconfiguration directive.
