HTTP_REFERER
ok, got my login script, and once they login, i want to send the browser back to the page they came. Although, i have login.php which sends it to login2.php. So if i just use $HTTP_REFERER then it sends it back to login page. Is there anyway you can send it back 2 REFERERS so to speak?

hmmm...

you might want to look into javascripts history object. I think it would be something like window.history.go(-2)

RE: HTTP_REFERER
I wrote some code to do this in php once. Essentially, I wrote a function that used the array_push and array_pop functions to create a stack of pages the person has gone to in the website. And then I could redirect them back x number of pages by popping that many off the stack and using the value in header('Location: ')... No need to rely on JS.

Cheers,
Keith.

RE: HTTP_REFERER
I've got an idea for you, this is what I did this morning...

On the login form I put a hidden input:

<input type='Hidden' name='page' value='<? echo $_SERVER['PHP_SELF']; ?>'>

Then in the login.php:

*check login, send cookie*
<html><body><head>
<?
if ($plain == "Login ok."){
echo "<META HTTP-EQUIV='REFRESH' CONTENT='1;URL=" .$HTTP_POST_VARS['page'] ."'>rn";
}
?>
</head>
<body>
<? echo $plain; ?>
</body>
</html>

That will redirect them to their last page and alow you to get the new cookie info.

RE: HTTP_REFERER
I havnt tried your code yet micah, but from the looks of it, it would just send them back to the page they came from. I wanted to send them back two pages i did figure it out though, so just in case anyone is interested how, i'll post it here:
You create the hidden field in the form, and make its value $HTTP_REFERER, and then when you redirect them on the next page:
php Code:
Original - php Code 
  1.  
  2. header("Location: <?= $_POST['referer'] ?>

so similar to yours micah, but instead of PHP self i used referer
