Var: Added $request_uri (as in NGINX).
This supports a new variable $request_uri that contains the path
and the query (See RFC 3986, section 3). Its contents are percent
encoded. This is useful for example to redirect HTTP to HTTPS:
{
"return": "301",
"location": "https://$host$request_uri"
}
When <http://example.com/foo%23bar?baz> is requested, the server
redirects to <https://example.com/foo%23bar?baz>.
