Hi, I have a forking server that uses standard sockets ( use Socket ) and accepts new connections like: 
my $client = accept( SESSION, SOCK );

[download]
When we accept a new session, we can read and write to the socket through the <SESSION> filehandle. Like so: 
while( $newmessage = <SESSION> ){
   #do something
}

[download]
or 
print SESSION "Here is your reply\n";

[download]
Everything works great, except I am not sure how to detect a dropped connection when working with the filehandle that I got from accept().

Once the client connects, the server starts processing some information and does not talk on the socket for a while. Sometimes the client decides they dont want to wait for results, so they disconnect. I would like to know when this happens so that I can stop processing the request. I dont mind checking it every couple of iterations, but I don't know the procedure.

I tried googling but nothing useful came back right away, so I am putting it in your hands!

Thanks
