nginx 0.3.10 *) 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.
