Special Cases

proxy_pass to a static direction (path)

"proxy_pass" cannot have URI part in location given by regular expression

location /go404 {
    rewrite ^ /404$1 break;
    proxy_pass http://bk$uri;
}

Append a querystring to redirection

If a replacement string includes the new request arguments, the previous request arguments are appended after them

rewrite ^ http://test.example.com$uri?test=1 permanent;
