How to secure a Drupal site

Awhile back, I was working on a private Drupal website for members only. Now, Drupal has a module called Secure Site which can be used for this. However, Secure Site throws up an HTTP 401 error to request authentication from the user. If you've ever seen a "enter username and password" box pop up in your browser, that's an HTTP 401 error. That's okay, but I don't think it's the best UI out there. I wanted something a little user-friendlier.
So, I came up with the code below. Put it in your index.php file (or better yet, in a file included by index.php) right after the call to drupal_bootstrap(). It will redirect all but a certain subset of pages to the login page, and prompt users to log in.
<?php
$path = getenv("SCRIPT_URL");
//
// If a user is not logged in, they can only access certain unrestricted pages.
//
if ($user->uid == 0) {
if (
//
// strstr() is called for efficiency. Keep in mind that ANY path that matches
// these strings will be allowed to anonymous users. So if you have something
// like "/userlist", an anonymous user can view that. I warned ya!
//
!strstr($path, "user")
&& !strstr($path, "how-to-join")
&& !strstr($path, "contact")
) {
form_set_error("", "You must be logged in first.");
drupal_goto("user");
}
}
?>Enjoy!
