Is it possible to change the $_SERVER['HTTP_HOST'] in htaccess? [closed]

Question

I have a sub-domain ABC.mydomain.com whose $_SERVER['HTTP_HOST'] I would like to change to another domain anotherdomain.com. Anotherdomain.com is one that I own too. Is it possible to globally change this variable ($_SERVER['HTTP_HOST']) using .htaccess? If so, how?

Answer 1

Probably isn't the most convenient solution (not sure if there is a way to do this straight through .htaccess), but I would try this:

# .htaccess
php_value auto_prepend_file alter_host.php

# alter_host.php
<?php
    $_SERVER['HTTP_HOST'] = 'anotherdomain.com';
?>

It caused some issues with me through the Laravel framework, but it worked with a simple site..so I'd give it a go.

You can't change the $_SERVER variable using .htaccess, as you can read there http://httpd.apache.org/docs/2.2/howto/htaccess.html. I think your real need is to redirect the page to a new domain. Try adding this line in you .htaccess file:

Redirect 301 ABC.mydomain.com http://example.com/newdirectory/
