Changes with nginx 0.8.40 07 Jun 2010

    *) Security: now nginx/Windows ignores default file stream name.
       Thanks to Jose Antonio Vazquez Gonzalez.

    *) Feature: the ngx_http_uwsgi_module.
       Thanks to Roberto De Ioris.

    *) Feature: a "fastcgi_param" directive with value starting with
       "HTTP_" overrides a client request header line.

    *) Bugfix: the "If-Modified-Since", "If-Range", etc. client request
       header lines were passed to FastCGI-server while caching.

    *) Bugfix: listen unix domain socket could not be changed during
       reconfiguration.
       Thanks to Maxim Dounin.
