how to terminate HTTP connection ?

i'm trying to write a script that will trigger other scripts on other sites

something like this

for ($i=0; $i<20; $i++) {
file_get_content("http://www.myothersite.com/file$i.php");
}

PHP:

however, those other scripts take a while to execute and i don't want my trigger script to wait that long. So i want to terminate the connection as soon as i receive a couple bits .

In other words - basically what i need is just to make a call to those remote scripts and imediately terminate the connection and make the call to the next script

any idea ?

 

header("Connection: close");

 

i need to terminate the connection on the receiver's side not on the sender's side
