fseek() on socket

I communicate with localhost.

So long as the machines are on the same local subnet, you can run ethereal on any of them, and see all local traffic no matter which machine originated it.

None of the machines on our network have Ethereal.

It turns out that the Content-Range header is a response header. To send a range request you need to send the Range header. Example:

Code:

   $out = "GET /bs.html HTTP/1.1\r\n";
   $out .= "Accept: */*\r\n";
   $out .= "Range: bytes=3000000-3000999\r\n";
   $out .= "Host: localhost\r\n";
   $out .= "Connection: Close\r\n\r\n";

This works on my machine running Apache 2.0.52. However, when I connect to the remote site, which runs Apache 1.3.33, range requests do not work; the entire file is returned. Doesn't Apache 1.3.33 support HTTP 1.1? Here is the request I send:

Code:

   $out = "GET /blog/index.php?p=48 HTTP/1.1\r\n";
   $out .= "Accept: */*\r\n";
   $out .= "Range: bytes=3000000-3000999\r\n";
   $out .= "Host: brokensaints.com\r\n";
   $out .= "Connection: Close\r\n\r\n";

This is the response header I get:

Code:

HTTP/1.1 200 OK

The Range requests, however, work for static pages fine. This is obviously dynamic.
