nginx-0.1.15-RELEASE import *) Bugfix: the error while the connecting to the FastCGI server caused segmentation fault. *) Bugfix: the correct handling of the regular expression, that has different number of the captures and substitutions. *) Feature: the location, that is passed to the FastCGI server, can be regular expression. *) Bugfix: the FastCGI's parameter REQUEST_URI is now passed with the arguments and in the original state. *) Bugfix: the ngx_http_rewrite_module module was required to be built to use the regular expressions in locations. *) Bugfix: the directive "proxy_preserve_host on" adds port 80 to the "Host" headers, if upstream listen on port 80; the bug had appeared in 0.1.14. *) Bugfix: the same paths in autoconfiguration parameters --http-client-body-temp-path=PATH and --http-proxy-temp-path=PATH, or --http-client-body-temp-path=PATH and --http-fastcgi-temp-path=PATH caused segmentation fault.
