URL rewrite override in Drupal
Drupal 6 introduced a new automagical function for rewriting URLs output through most of Drupal called custom_url_rewrite_outbound().
The path module already gives you the ability to alias paths to different places, but only within the same domain. To redirect a path that has already been aliased, or to a different subdomain or different location altogether, adding custom_url_rewrite_outbound() to settings.php might be a solution for you. Since this is not a hook, it can only be used once per Drupal installation, which is part of why settings.php is a recommended place for it.
This code example will rewrite user, user/register, about, advertise, forum, and blog to other domains by changing the base_url by reference. Any URL on the site that passes through Drupal's core url() function will be rewritten, even if it was aliased by the path module.
<?php
function custom_url_rewrite_outbound(&$path, &$options, $original_path) {
$url_rewrites = array(
// Drupal core paths
'user' => 'http://users.mysite.com',
'user/register' => 'http://users.mysite.com',
// general information paths
'about' => 'http://www.mysite.info',
'advertise' => 'http://www.mysite.info',
// other
'forum' => 'http://forums.mysite.com',
'blog' => 'http://blogs.mysite.com',
);
while (list($key, $value) = each($url_rewrites)) {
if ($path == $key || $original_path == $key) {
$options['base_url'] = $value; // updated by reference
$options['absolute'] = TRUE;
break;
}
}
}
?>

Changing default url's for security reasons
Excellent work, I can see how this can be useful for subdomains.
Now imagine if I want to change a default path from: www.example.com/admin to: www.example.com/secret-admin
..and when someone enters www.example.com/admin I want it to redirect to the front page.
A version of this for D5 can be found here, using 'custom_url_rewrite': http://www.drupalcoder.com/story/9-drupal-custom-url-rewriting-change-th...
Any ideas how to go about this in D6?
Also available in D5!
For those of us still developing D5 sites, the same functionality is available as custom_url_rewrite(). It includes both the outbound and the inbound functionality, which is a bit confusing, hence the split into two functions for D6. One thing I like to do with it is substitute "article" (or "content") for "node" sitewide. I hadn't thought about using it in this particular way, though. Great tip.
Good explanation. Seen this
Good explanation. Seen this in the API, but couldn't never grasp what I could actually do with it.
