how to preventing sharing persistent socket with two different tabs of same browser

golden_boy615 · 03-25-2012, 05:09 AM

hello
I have problem with persistent socket in php my problem is when I open a new tab of firefox, opera or chrome (but not Internet explorer) they share an existing persistent socket which is opened with pfsockopen function by first tab and does not open new persistent socket (which is Internet explorer does) what should I do in firefox (or related explorers) or in my code to open new socket for each new tab.
this is my sample code:

PHP Code:



<meta http-equiv="refresh" content="2;url=?"> 
<?php 
error_reporting(0); 
@ini_set(‘display_errors’, 0); 
$fp = pfsockopen("192.168.1.30",7778, $errno, $errstr, 30); 
stream_set_blocking ( $fp , 0 ) ; 
if ($fp) { 
$out = "Device-1;"; 
fwrite($fp, $out); 
$out_put = fread($fp, 2048); 
echo $out_put ;     
}else{ 
echo '0000'; 
} 
?>

I would suggest that this behaviour is positive and should not be deemed to be a "problem" at all. Your PHP code certainly has no say in how the browser chooses to manage the connections. You can tell a connection to be kept alive, or you can force it to shut, andything past that is outside of the remit of HTTP/1.1.

Does opening a new firefox window do anything? I presume not, but it's worth checking. Other than that, load a different profile, or a different browser. Privay modes are useful for quick ways of testing two different sessions from the same browser instance too.

but I do not want this behavior in firefox (internet explorer does not do that) how can I prevent it??

you can't. you need to redefine your requirements and approach for this to not matter. I don't feel it is reasonable for you to want this.

There are lots of things that don't behave the way we want them to. You can either hold your breath until you turn blue or they change it (what shade of blue do you like?), or you can adapt. Most of the rest of us find that adapting is a big part of the challenge. It's part of writing applications for portability.
