nginx-0.1.15-RELEASE importrelease-0.1.15

    *) Bugfix: the error while the connecting to the FastCGI server caused
       segmentation fault.

    *) Bugfix: the correct handling of the regular expression, that has
       different number of the captures and substitutions.

    *) Feature: the location, that is passed to the FastCGI server, can be
       regular expression.

    *) Bugfix: the FastCGI's parameter REQUEST_URI is now passed with the
       arguments and in the original state.

    *) Bugfix: the ngx_http_rewrite_module module was required to be built
       to use the regular expressions in locations.

    *) Bugfix: the directive "proxy_preserve_host  on" adds port 80 to the
       "Host" headers, if upstream listen on port 80; the bug had appeared
       in 0.1.14.

    *) Bugfix: the same paths in autoconfiguration parameters
       --http-client-body-temp-path=PATH and --http-proxy-temp-path=PATH,
       or --http-client-body-temp-path=PATH and
       --http-fastcgi-temp-path=PATH caused segmentation fault.
