problems with fopen and IP

doublethink

I'm working on a kind of proxy wich uses fopen() to get remote urls.

The point is that fopen works fine when called by the script on my home server, while it returns a kind of 404 when called by the same script (on the same url) on my job server.

Both WinXP and Apache and same apache and php.ini conf.

The problem seems to exist only for certain domains, while other url work fine on both machines.

Hope you can give me a suggestion.
Thanks.

If you're trying to make php act like a browser, which you are, then you should be using [man]curl[/man] and not fopen.

Thanks, I'll try that.

But why is this problem occurring only for some url and only from a certain IP?

Do these URLs load when you request them directly with your browser at work ? How do these URLs look like (GET parameters) ?

And is a "kind of 404" a 404 reponse or only something like a 404 response?

doublethink

These URLs work fine if I open them directly at work and if I fopen them at home....they do not fopen at work (while other URL fopen at work without problems).

They are in the form http://www.something.com/somethingelse

The response I have is a 404, even though the URLs exist.

some cookies are probably being set which you could grab and sendback with curl

To test if it works at all try the base url instead like

$fp = fopen("http://www.thedomain.com/");

I'd suggest to use curl instead like mentioned by drawmack.

Try also using fsockopen() to request the page on both servers, then look at the http headers that are returned. There may be clues there.
