    HTTP GET not working ...why?

    I've got a program that accesses the following URL
    with a GET command but the server responds with 400.
    Is there something unusual about this site?

    Thanks.

      The web server might be rejecting the program because of
      unknown browser type. The site is flash based so it must be
      checking for browser compatibility.

      I would recommend using Ethereal to check the difference
      between the HTTP get sent by a regular browser and your
      program.

          Are you sending the "Host: www.nasa.gov" header? I get a 400 response
          if I leave it out, but the GET works when I put it in.

          The server is presumably doing virtual hosting, so it needs to know the
          hostname of the URL in order to find the proper page.

              I wasn't sending Host.

              Incidentally, I've got another bizarre host:

              Web Client Programming with Perl: Chapter 3: Learning HTTP
              http://www.oreilly.com/openbook/webclient/ch03.html


              It sends back HTML which doesn't look like what later
              appears in the browser, e.g. title= MakeZine.com

              Do you have any idea what's going on with that?
              Thanks.

                  Sounds like you might have been hijacked. If you're on a windows system,
                  take a look at your hosts file and see if there is anything suspicious in
                  it. See <http://www.mvps.org/winhelp2002/hosts.htm> for more info. Also
                  run a spyware checker, Spybot Search & Destroy is very good
                  <http://security.kolla. de/>, and I would also run a virus check.

                      Nope, that's not it. Incidentally does Windows have an equivalent
                      to Linux's /etc/hosts.deny?

                      Thanks.

                          Please learn how to quote the message you're responding to with the new

                          I just did:

                          telnet www.oreilly.com 80
                          GET /openbook/webclient/ch03.html HTTP/1.0
                          Host: www.oreilly.com

                          and the HTML it sent looked like it would produce the page I saw with my
                          browser. It began with:

                          HTTP/1.1 200 OK

                          I don't think so, but I'm not a Windows expert.
