detect www

[dlf1987]

Hi, how do i detect if the user is logged on to my site through http://www. or just http://?

 

I want to be able to redirect people to http://www.

 

The main reason why im asking is because my cookies from the http:// domain, dont show up on http://www.

 

I think theres a way with apache rewrite, but i run PHP on Windows IIS6 so i dont think rewrite works.

 

Thanks!

You could use $_SESSION['HTTP_REFERER'] to get the last full address, if it's not your own then you redirect, otherwise you check if it is how you want it.

 

P.S. Use header to redirect

hmm or is there a way for the same cookie to be read by both http:// and http://www?

Thanks for the help, but i figured it out from php.net...

 

http://uk3.php.net/manual/pl/function.setcookie.php

 

"To make the cookie available on all subdomains of example.com then you'd set it to '.example.com'. The . is not required but makes it compatible with more browsers. Setting it to www.example.com  will make the cookie only available in the www  subdomain. Refer to tail matching in the » spec for details."

You could use .htaccess to forward all traffic to your non www site.

Sorry, this should of been:

$_SERVER['HTTP_REFERER']

you can do .htacess

my webhost has a FAQ and it has that in it, here is what it says:

 

You are able to make your web site always appear with the address www.lamezz.com.

 

Please use the follwoing code in a .htaccess file to redirect your url

from lamezz.com to www.lamezz.com.

-------------------------------

Options +FollowSymlinks

RewriteEngine on

RewriteCond %{HTTP_HOST} ^lamezz.com [NC]

RewriteRule (.*)$ http://www.lamezz.com/$1 [L,R=301]

-------------------------------

 

You are able to make this redirection for any of your domain names on your Servage account.

 

since I was logged on with my account it uses www.lamezz.com, just replace it with yours, I have tried it before, and it works!
