fsockopen behaviour?

[hsingist]

Hi,
I'm experiencing this weird behaviour, I'm currently using fsockopen to send a GET string across to another script on the same server but I have to wait consistently for around 15secs before I get any response back from the other script.

If I use the same method but call a basic html page itself, the response is instant.

Now I changed was from calling 'index.html' to 'index.php' with the content being the same except adding php tags and the server response back at around 15secs. All I can conclude from this is that somehow by calling a file with a .php extension will slow the response but this shouldn't be the case right?

Anyone has any idea why? I'm at my wits end on this. Please help!

Thanks a million in advance!

You have to add "Connection: close" in the HTTP header that you send along with the request.

Find some documentation about HTTP 1.1 for more info

Hi,
I did add the "Connection: Close". I'm using the same declarations when calling the php and a simple html. The html call returns instantly whereas the php call is always around 15secs.

post your code here ....

Here is the code. If I just substitute the path from '/index.php' to '/index.html' the response is instant.

---

function GetToHost($host,$port,$path)
{

$fp = fsockopen($host,$port);
if($fp) {
fputs ($fp , "GET $path HTTP/1.1\r\n");
fputs ($fp , "Host: $host\r\n");
fputs ($fp , "Connection: Close\r\n\r\n");

	  while (!feof ($fp )) {
           $res .= fgets ($fp ,128 );
      }
       //printf ("Done!\n");
      fclose ($fp );
      return $res ;
 } else {
      return "There is a problem connecting to the server.";
 }

} //End function

$host = '127.0.0.1';
$port = "80";
$path = "/index.php?name=testname";

$result = GetToHost($host,$port,$path,$data_to_send);

print $result;

Thanks!

you have to write "Connection: close" (close with a lower c)

[cosminb]

or simply put

 fputs ($fp , "GET $path HTTP/1.0\r\n");

instead of

 fputs ($fp , "GET $path HTTP/1.1\r\n");

Damn! You're Good! hehe 😃 It solves it!
Any idea why using HTTP/1.1 the previous way doesn't work other than the 'Close' versus 'close'?

Thanks another million! 😃

The server didn't understood the value "Close" so it ignored it. So the connection remained active untill it reached it's timeout(default is usually 15 seconds).

In HTTP 1.0 the server closes the connection after the scripts ends.
