How to configure Trusted_Host_Settings for subdomains?
The documentation does not give an example of a subdomain.
For example, I have an Add-On domain that points to website.info, but the subdomain is mainsite.com/website.info

Did not work. Invalid hostname for this computer. Perhaps using the term subdomain caused confusion. The pattern I have to match is: domain.com/subdomain.info Sites in folders under the main domain.– DavidApr 28, 2018 at 17:58

It's actually documented in settings.php file as in examples:
Drupal 8.5.x
https://cgit.drupalcode.org/drupal/tree/sites/default/default.settings.php?h=8.5.x#n712
<?php
$settings['trusted_host_patterns'] = [
'^example\.com$', // Matches naked domain only.
'^.+\.example\.com$', // Matches any subdomains.
'^subdomain\.example\.com', // Matches a specific subdomain.
];
You can easily define any naked or sub-domain, as long as defined regex pattern matches them correctly.

Good catch The other things I have seen did not provide a pattern like this. Thanks.– DavidApr 27, 2018 at 21:43

Did not work. domain.com/subdomain.info Matching the folder structure of sites under the main site.– DavidApr 28, 2018 at 18:01

You really should read the documentation for the
trusted_host_patternssetting. As the name suggests, it's for setting up trusted hostnames. If you don't know the difference between host and path, I also recommend reading up What is a URL? at MDN.– osmanApr 28, 2018 at 18:38 -
I found when using trusted_host_patterns in a development area with a deeper structure, I needed to add multiple lines like so: $settings['trusted_host_patterns'] = array( '^example\.com$', '^work\.example\.com$', '^dev\.work\.example\.com$', ); Sep 22, 2021 at 15:10
