I doubt that that is the URL that you are seeing but it is interesting to see that
that server seems to be _very_ particular about the syntax it gets.
E.g. normally we can simulate an HTTP browser connection using telnet
to a site's port 80 with as little as GET / though sometimes we have to switch to
GET / HTTP/1.1 plus Host: fido.ca In this case even the latter is coming
back with an HTTP 500 error response:
<H3>From RFC 2068 <i>Hypertext Transfer Protocol -- HTTP/1.1</i>:</H3></FONT>
<FONT FACE="Helvetica" SIZE="3"><H4>10.5.1 500 Internal Server Error</H4></FONT>
<P><FONT FACE="Courier New">The server encountered an unexpected condition

So this at least gives you the RFC number of the specification that
the other section number that you saw will be coming from...
(Live Search for
A better tool to use both for testing and diagnosis is Fiddler2.
With it we can try adding a User-Agent and whatever else
the host server seems to need to simulate a successful request...
Hmm... the server's not even satisfied when I replace Fiddler's User-Agent
with the real IE7 User-Agent in Fiddler's Request Builder. Very unusual.
Well, Fiddler shows that there are 4 other headers which could
be sent to exactly simulate what IE7 would send with its request.
I leave finding which ones of those aren't absolutely required by
that server as "an exercise for the reader". ; )
