browser's back button

[padma]

I am using the following code for the redirect.

echo "<script>location.href='http://www.yahoo.com';</script>";

Once it redirects to yahoo.com, if I use browser back button to go back to the previous page, it's going back and doing the redirect again. Is there a way to stop redirection, if I use browser's back button.

Thanks.

not when the page you're going back to says "redirect to yahoo". Obviously.

I don't know what you're trying to do exactly, but you might want to check the value of getenv("HTTP_REFERER") and use

if ( strstr( getenv('HTTP_REFERER'), "mydomain.com" ) ) {
    header('Location: http://www.yahoo.com');
}

to redirect if the last page was on your site.

I'm not sure if this will work or not but try

<?
header("location:http://www.yahoo.com");
?>

I know it works for redirects on the local server, I don't know about outside links...

Hope this helps

the 'location' header requires a complete url i.e. 'http://www.mydomain.com/otherpage.php' NOT just 'otherpage.php' or '/otherpage.php'. I know it often works without the full url, but that's not to say it always will, because that's not the standard.
