The requested URI for the request.
The returned URI is reconstructed by using http-header fields, to access otherwise lost information, e.g. host and scheme.
To reconstruct the scheme, first 'X-Forwarded-Proto' is checked, and then falling back to server type.
To reconstruct the host, first 'X-Forwarded-Host' is checked, then 'Host' and finally calling back to server.
Uri get requestedUri;
