Yes.

You're asking in the wrong place, though, as I'm sure you'll be told 14
times by 12 other people. :)

http://www.w3.org/Protocols/#Specs for some serious study on the subject.

Further to what I wrote; taken from RFC 2616:

The most common form of Request-URI is that used to identify a
resource on an origin server or gateway. In this case the absolute
path of the URI MUST be transmitted (see section 3.2.1, abs_path) as
the Request-URI, and the network location of the URI (authority) MUST
be transmitted in a Host header field. For example, a client wishing
to retrieve the resource above directly from the origin server would
create a TCP connection to port 80 of the host "www.w3.org" and send
the lines:

GET /pub/WWW/TheProject.html HTTP/1.1
Host: www.w3.org

followed by the remainder of the Request. Note that the absolute path
cannot be empty; if none is present in the original URI, it MUST be
given as "/" (the server root).

Hope that helps you out.

This is *usenet* (newsgroups), to which using Google is just one way to
access it. It's usenet that you want to find out how to use. Don't pick
up bad habits from web forums.

Going from memory, there's a newsgroup with "newusers" as part of its name
which has regular postings about how it all works, for new users to read.

Off-topic, but...

For HTTP/1.1, the Host: header is a required field. In HTTP/1.0, it is not
even defined as a header. However, the Host: header became widely implemented
in browsers before HTTP/1.1 to support name-based virtual web server hosting.

So while your server *may* never see a HTTP request without a Host: header, it
can certainly happen, so you should consider what to do in that case. Or if
the Host: header provided makes no sense, or contains some type of system
commands...

That would be "news.announce.newusers". Used to be most newsreaders were
configured to come up subsciribed to that group until the user unsubscribed.
Too bad that Web-based Usenet access providers can't be bothered to do that.
