ah okay, looks legit.
from http://www.ietf.org/rfc/rfc2616.txt:
-------
5.1 Request-Line

    The Request-Line begins with a method token, followed by the
    Request-URI and the protocol version, and ending with CRLF. The
    elements are separated by SP characters. No CR or LF is allowed
    except in the final CRLF sequence.

         Request-Line   = Method SP Request-URI SP HTTP-Version CRLF

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


.....

The absoluteURI form is REQUIRED when the request is being made to a
    proxy. The proxy is requested to forward the request or service it
    from a valid cache, and return the response. Note that the proxy MAY
    forward the request on to another proxy or directly to the server 
specified by the absoluteURI

....

An example
    Request-Line would be:

        GET http://www.w3.org/pub/WWW/TheProject.html HTTP/1.1
-------
sorry for the noise, seems -I and -u can be used to request from a proxy 
then, not too sure about socks either.
