Add www to url

[olokiop]

I ran over a script at these forums a while ago that allowed someone to put the www. in front of the url if a visitor did not type it in. I have spent the last 3 hours searching for that script again with no luck. Anyone know how to do this or know where it is posted in these forums?

FYI it was a refresh based on a url if statment.

Have you considered doing it in javascript, visual quickstart to Javascript has exactly that as an example.
alternatively, have a .inc file in the same directory on the server as your index.html page on the web

not yet, but will post this there as well.

Do you mean something like this:

<?php if ($_SERVER['HTTP_HOST'] != "www.example.com") {
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com".$_SERVER['REQUEST_URI']);
exit; 
}
else {
// normal page headers
};
?>

The above sends a 301 Permanent redirect if the URL isn't the www. version (or is anything else), but retaining the full URL details from after the domain name.

Not what I ment.

Say a user types 'cnn.com' into their browser. I need the browser or the server to know this and send them to 'www.cnn.com'.

301's will not work for this.

anything like this? not tested though..

if (substr($_SERVER['HTTP_HOST'], 4)!= "www."){
$url = "http://www." . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header("Location: $url");
}

That is exactly what my quoted PHP code does.

Ah i see encyclo, sorry for the confusion.

I will run tests as soon as I get home.
