Issue resolved... For some reason if the $request_uri was empty, the redirect failed
because it was going to itself. I enclosed the redirect around an if statement
checking the request_uri variable. BTW, $request_uri is a hidden form variable that
captures the actual $REQUEST_URI global variable when the login form appears. This
allows me to redirect the user to the requested page when they log in. Works like a
charm!!!
Sometimes in explaining the problem, I see the solution.

Subject: [PHP] Session Login and Redirect Problem
I am using Sessions with mod PHP4.0.6 with trans-sid set on. Everything works fine.
However, after loggin in, I want to automatically redirect the user to a specific
page if they came from an external site or were given a link via emal. I realize
that a session variable is not actually stored until the end of the script. So I used
the session_write_close() function to save the session before redirecting using the
header() function. It does not work. The session variable fail to be available after
redirection.
Any ideas?
================================================================
<?php
if (!session_is_registered("valid_user") && $session_login=="proc"){
if ($userid && $password) {
// if the user has just tried to log in
$query = "select * from auth_users "
."where auth_username='$userid' "
." and auth_password='$password' and active='Y'";
$result = mysql_query($query) or die("MySQL Login Error: ".
mysql_error() );
if (mysql_num_rows($result) >0 ) {
// if they are in the database register the user id
$valid_user = $userid;
$valid_group=mysql_result($result,0,"auth_group");
$valid_perms=mysql_result($result,0,"auth_perms");
$valid_auth_id=mysql_result($result,0,"auth_id");
session_register("valid_user");
session_register("valid_group");
session_register("valid_perms");
session_register("valid_auth_id");
/* Redirect browser */
session_write_close();
header("Location: http://".$SERVER_NAME.$request_uri);
exit; // exit script
} else {
$invalid_login= "Invalid login: Could not log you in...
<!--ERROR: $dbname <P> $query-->";
}
}
}
?>
