Get URL from an Header() redirected site

[Anon]

Problem:

I have a page with hundrets of links like:
<a href="/linkto.php?id=35>...

linkto takes the link with id 35 from an database and do a Header("Loction: ...") to the linked page.

So, from my second server I will parse the linkpage and get the real url from an link.

If i try:
$fp=file("/linkto.php?id=35")
I get the content of the URL that the linkto script links to . it works for the content.

So I had the Idea to get the HTML Headers and tried to open a socket on domain www.domain.com and path /linkto.php?id=35 but the opened socket (witch fsockopen) cant understand parameters like ?id=35 and returs a failure.

So, how to get the URL where the linkto.php script links to ?

u have to open the socket with the web server then u have to send an http header like this:
$w_socket=fsockopen("IP_ADDR",8090,&$errno,&$errstr,10000);
fputs($w_socket,"GET /page.php?id=35 HTTP/1.1\n\n");
i did it and it works....

ehm then u have to read from the socket with fgets as a file...
while(foef($w_socket))
fgets(etc etc etc);

Right, but I get an 400 Bad Request of the Server who host that linking script and not the header information from the right destination 🙁
