nginx 0.1.17
*) Change: the ngx_http_rewrite_module was rewritten from the scratch.
Now it is possible to redirect, to return the error codes, to check
the variables and referrers. The directives can be used inside
locations. The redirect directive was canceled.
*) Feature: the ngx_http_geo_module.
*) Feature: the proxy_set_x_var and fastcgi_set_var directives.
*) Bugfix: the location configuration with "=" modifier may be used in
another location.
*) Bugfix: the correct content type was set only for requests that use
small caps letters in extension.
*) Bugfix: if the proxy_pass or fastcgi_pass directives were set in the
location, and access was denied, and the error was redirected to a
static page, then the segmentation fault occurred.
*) Bugfix: if in a proxied "Location" header was a relative URL, then a
host name and a slash were added to them; bug appeared in 0.1.14.
*) Bugfix: the system error message was not logged on Linux.
