Added clearing of r->valid_unparsed_uri on internal redirects. This resolves issue with try_files (see ticket #70), configuration like location / { try_files $uri /index.php; } location /index.php { proxy_pass http://backend; } caused nginx to use original request uri in a request to a backend. Historically, not clearing of the r->valid_unparsed_uri on internal redirect was a feature: it allowed to pass the same request to (another) upstream server via error_page redirection. Since then named locations appeared though, and it's time to start resetting r->valid_unparsed_uri on internal redirects. Configurations still using this feature should be converted to use named locations instead. Patch by Lanshun Zhou.
