As mentioned elsewhere, in HTTP 1.0 you get a full URL in the opening line. In HTTP 1.1 you get the path component in the opening line and the host part in the Host: header of the request. Have a read of RFC2616 (which defines HTTP 1.0): http://tools.ietf.org/html/rfc2616 It has sections on proxies, too, outlining which they must do beyond what a plain HTTP server must do (not much, but a few things, and there are proxy-specific authentication fields available too): Proxy Servers http://tools.ietf.org/html/rfc2616#section-8.1.3 Proxy Authenticate http://tools.ietf.org/html/rfc2616#section-14.33 Cheers, -- Cameron Simpson <c...@zip.com.au> There's two kinds of climbers...smart ones, and dead ones. - Don Whillans -- http://mail.python.org/mailman/listinfo/python-list
