Changes with nginx 0.5.17 02 Apr 2007
*) Change: now nginx always returns the 405 status for the TRACE method.
*) Feature: now nginx supports the "include" directive inside the "types" block.
*) Bugfix: the $document_root variable usage in the "root" and "alias" directives is disabled: this caused recursive stack overflow.
*) Bugfix: in the HTTPS protocol in the "proxy_pass" directive.
*) Bugfix: in some cases non-cachable variables (such as $uri variable) returned old cached value.
