Example 2: https/1.1

Note: The "no rewrite" rule prevents the proxy from changing the
      meaning of the request when the origin server is improperly using
      a non-reserved URI character for a reserved purpose.  Implementors
      should be aware that some pre-HTTP/1.1 proxies have been known to
      rewrite the Request-URI.

Example 3: https/1.1

Request-URI    = "*" | absoluteURI | abs_path | authority
