What is the client server sequence for setting a cookie?
How can I check if a browser accepts cookies?

Nathan Wallace,
Here is the cookie setting sequence in PHP:
Client Server
requests page
gets request
sets cookie in reply
sends reply
gets reply (with cookie)
sets cookie on machine
sends new request (with
cookie included)
gets request
finds cookie in request
sets variable in script
runs script
The server has to interact with the client to be able to set a cookie or
determine if it has been set.
From http://www.php3.com/manual/function.setcookie.php3
<?php
$status = 0;
if (isset($myTstCky) && ($myTstCky == "ChocChip")) $status = 1;
if (!isset($CCHK)) {
setcookie("myTstCky", "ChocChip");
header("Location: $PHP_SELF?CCHK=1");
exit;
}
?>
<html>
<head><title>Cookie Check</title></head>
<body bgcolor="#FFFFFF" text="#000000">
Cookie Check Status:
<?php
printf ('<font color="#%s">%s</font><br>;',
$status ? "00FF00" : "FF0000",
$status ? "PASSED!" : "FAILED!");
?>
</body>
