I have a custom script that since my move to Drupal has been hard-coded in the core index.php file.

I realize this is not the Drupal way and it has been a pain to ensure that this code is added every time drupal core is updated...

To correct this, I wish to turn it into a module, however, the functionality of this code has to specifically be loaded before anything else as I need to be able to perform a meta redirect if needed....

Basically I have the script check to see if the URL has a variable stored which triggers the redirect, so if a different website is linking to mine with this variable, the script then redirects the user to whatever page on my site I want... there are other things the script does, like logging the referral site and such, but I don't think that it is relevant to this question.

While I have been playing with altering strings and links with custom Drupal modules, I have no idea what hook I would use to implement this, or even if its possible to do with Drupal other than hacking up the index.php

Any ideas?

hook_init (http://api.drupal.org/api/function/hook_init/6) called for each page load in drupal,
If you want even early than hook_init, you can use hook_boot(http://api.drupal.org/api/function/hook_boot), may this help you.

Use hook_page_build() instead. hook_init is run for every request, including ajax callbacks etc., and why would you want to be inserting arbitrary javascript for those?

Metatag should be in core.

Once you decide which hook works for you, add the JS using drupal_add_js script
