Configure your webserver so that the default page served when an incoming request is something other than your default Drupal installation, such as an error page.Use a specific sites//settings.php and let $base_url be detected dynamically - this has the implication of letting Drupal respond to all subdomains of which may or may not be a benefit.One way to stop that is just to set a permanent value. While the dynamic detection can be a handy feature it can also cause problems. You can set a specific domain as your $base_url in sites/default/settings.php.Solutions 3 and 4 also work for Drupal 8+. You should pick and choose as appropriate for your environment.

There are at least four potential solutions to this problem, though not all are necessary to stop the problem from happening. The example below will allow the site to run from all variants of and, with all subdomains included. you run your site from and ), you should specify all of the host patterns that are allowed by your site. If you are running multisite, or if you are running your site from different domain names (e.g. If you want to match a dot, it must be escaped by a backslash as in the example above. In the example below, the site is only allowed to run from $settings = [Ībout regular expressions used in this example: If the Host header of the HTTP request does not match the defined patterns, Drupal will respond with HTTP 400 with a message The provided host name is not valid for this server. This should be an array of regular expression patterns, without delimiters, representing the hosts you would like to allow. To enable the trusted host mechanism, you enable the allowed hosts setting $settings in the settings.php file (the sites/default/settings.php file inside the webroot directory). Protecting against HTTP HOST Header attacks Protecting in Drupal 8 and laterĭrupal 8 and later versions can be configured to use Symfony's trusted host mechanism to prevent HTTP Host header spoofing.
