This is an absolute URI and this is the standard http protocol:
- The scheme is used to determine the protocol, and eventually the port.
- The given host is translated into an IP address and connected to.
- http protocol transmits the host allowing the server to resolve a
possible virtual hosting.
- the path in the "get" request starts with a "/" and thus is absolute.
- A full URI (scheme:://authority/path) in the request line would be
valid only with a "connect" request and requires the server to act as a
proxy, which is not what you expect.

Thus the absolute URI request is perfectly OK :-)
