A web address I occasionally use gave me the following message a few days
ago:

ERROR 404 - NOT FOUND
From RFC Hypertext Transfer Protocol - HTTP/1.1 10.4.5 404 Not Found

Is there anything I can do to have my access to the web address restored.
It works on computers of others I know.

Your advice will be appreciated.

Azeez

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:

<HTML_Extract>
<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
which prevented it from fulfilling the request.</FONT></P>
</HTML_Extract>


So this at least gives you the RFC number of the specification that
the other section number that you saw will be coming from...

http://www.ietf.org/rfc/rfc2068.txt

(Live Search for
rfc2068
)


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". ; )
