nginx-0.3.10-RELEASE import

Browse Source 
*) Change: the "valid_referers" directive and the "$invalid_referer"
       variable were moved to the new ngx_http_referer_module from the
       ngx_http_rewrite_module.

    *) Change: the "$apache_bytes_sent" variable name was changed to
       "$body_bytes_sent".

    *) Feature: the "$sent_http_..." variables.

    *) Feature: the "if" directive supports the "=" and "!=" operations.

    *) Feature: the "proxy_pass" directive supports the HTTPS protocol.

    *) Feature: the "proxy_set_body" directive.

    *) Feature: the "post_action" directive.

    *) Feature: the ngx_http_empty_gif_module.

    *) Feature: the "worker_cpu_affinity" directive for Linux.

    *) Bugfix: the "rewrite" directive did not unescape URI part in
       redirect, now it is unescaped except the %00-%25 and %7F-%FF
       characters.

    *) Bugfix: nginx could not be built by the icc 9.0 compiler.

    *) Bugfix: if the SSI was enabled for zero size static file, then the
       chunked response was encoded incorrectly.
