nginx-0.3.10-RELEASE import
*) 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.
