php check domain name and then redirect

[forced]

Here is my issue in a nutshell. I have 2 domain names:
www.aacorvette.com is the primary
www.aandacorvette.com is the secondary and setup as a domain alias

I have an SSL for www.aacorvette.com and only want to use that one.

Right now I have this to check and see if the URL is aacorvette or aandacorvette and redirect if incorrect.

<? 
$aa = 'www.aacorvette.com';
$url = $_SERVER['SERVER_NAME']; 
if ($url != $aa)
{
  header('HTTP/1.1 301 Moved Permanently');
  header('Location: http://www.aacorvette.com');
}
?>

This seems to work OK, but if the user has http://aacorvette.com in the bar, it will forward them to the www.aacorvette.com address. (not that big of a deal)

I tried to find a funtion that would use a "contains string in variable" but I couldn't find a good way.

Is this the best way to do this? If so, is the best place to put the code in the tpl_main_page.php file?

Thanks!

I forgot to add that I am on a windows box so I can't use .htaccess and I am on v1.3.8a.

Try this:

<? 
// Must be www.aacorvette.com or will redirect
if ( $_SERVER['SERVER_NAME'] != 'www.aacorvette.com')
{
  header('HTTP/1.1 301 Moved Permanently');
  header('Location: http://www.aacorvette.com');
}
?>

strstr() is a "is string contained in string" function.

I'd be inclined to put it in the master /index.php file in the root of your site.


But better yet, I'd recommend researching your windows webserver configuration for smarter alternatives which would give you control similar to .htaccess. Your hosting company should be able to offer some ideas.

Thanks for the help guys! I tried using the strstr() but couldnt figure out how to make it work. Like if I needed to say true or false, etc. I will look further into something like a .htaccess file. In the meantime I am going to try Skip's way and put in the index.php. I can't believe I did all that with the variables and it was that easy!
