Stupid CURL question

[mbeals]

I have some equipment at remote sites that is managed by an appliance with an HTTP interface.  I'm working on an automated script to log into the HTTP interface and fetch the status of the attached equipment.  The appliance uses GET based, plain text authentication (not the best, but we have it IP locked over a secure link).

 

I can successfully connect to the appliance and fetch the HTML containing the info I need, but the session is hanging, and causing the appliance to lock out any other sessions for a period of time.  I know the session is hanging, because I can watch is stuck in ACK-FIN with lsof.  I think the problem is the session is being abandoned after the initial login and data fetch, so when I issue the logout command, it initiates a new session, leaving the old one hanging (making the appliance think I'm still logged in).

 

This is the code that I'm using:

 

<?php

$IP = 'xxx.xxx.xxx.xxx';
$user = 'admin';
$pass = 'xxx';

$login  = "UserID=$user&Pwd=$pass";

$info   = "HeadendStatus.htm?";

$logout = "LOGIN.htm?LOGOFF=LOG+OFF&";

//Fetch Status
$ch = curl_init("http://$IP/".$info.$login);

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);

$data = curl_exec($ch);

//Log out
curl_setopt($ch, CURLOPT_URL,"http://$IP/".$logout.$login);
$result=curl_exec($ch);

curl_close($ch);

// Process data.....
?>

 

So, any thoughts on how to simulate login->fetch data->log out with curl, or any other functions?

If you are  using a GET you dont really need curl. After you get the results and close curl try sending the url via something like file_get_contents("http://$IP/$logout$login");

Thanks.  strangely enough, just using a single file_get_contents() call worked perfectly.  No clue why CURL was giving me so many problems.
