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:

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/win2002/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
Google. It's in an Options menu I think.

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:

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