Problems with header redirect

BiGDUG

I am having problems with Header redirects on our site, I am using the following code to

<?
if($utm_source==="cj")
{
header('Location:'. $URL);
}
else
{
header('Location:index.php');
}

?>

This is designed so that one of our affiliates can pass the following url http://www.bigdug.co.uk/cj/?utm_source=cj&URL=http%3A%2F%2Fwww%2Ebigdug%2Eco%2Euk%2Facatalog%2FBudget%2Ehtml to the site and get redirected the url as specified in the variable URL.

This works fine when accessing the site using the affiliate link but when users just go to the site by going to www.bigdug.co.uk/cj (i have set up this directory so that i can test it) or bigdug.co.uk/cj/index.php it is just hanging in the browser.

It seems to be an issue with the redirect going to itself when you go through the else, if you change the page you are redirecting to to another page it works fine, so basically i need it to point to itself as I do not want to have to duplicate the homepage.

Any help gratefully received.

1. Make sure there is nothing (including spaces, tabs, or blank lines) before the first <?php tag of the file.

Make sure there is nothing in your code that generates any kind of output (echo, print, or text - including whitespace - not enclosed by <?php ?> tags) before your call to header().

Maybe something like this?

<?
if($utm_source==="cj")
{
  header('Location:'. $URL);
}
elseif(basename(__FILE__) != "index.php")
{
  header('Location:index.php');
}

?>

You do realize that your code is working as it should, right? You've created an infinite loop.

If the ELSE section is reached, you tell the script to redirect the user to... the same script. Thus, you start the entire process over again.
