If you are using Kalabox, you should have some basic conditionals that setup your settings.php to operate on Pantheon and your local Kalabox:

Non-Kalabox

If you aren't on Kalabox, you should setup something similar. Make sure you don't overwrite any of the existing Kalabox settings or Pantheon configuration:

301 Redirect to Single Domain

On most sites that are going live, we'll want to make sure all requests are directed to a single domain for ideal SEO and user experience. We do this with a permanent 301 redirect.

Full Settings.php Sample

Here is an example portion of a settings.php with environmental magic on Pantheon

There is an example 404 redirect config, and a redirect for a path part to a subdomain.

Also, a placeholder for 301 redirects.

note that there are 2 different ways to check the Pantheon environment, here – one for config, the other for web actions like redirects.

301 Redirect to Single Domain

On most sites that are going live, we'll want to make sure all requests are directed to a single domain for ideal SEO and user experience. We do this with a permanent 301 redirect.

In this example, we're making sure that the default Pantheon domain AND www.mysite.com are redirected to the non-www domain:

Code Block

language	php
theme	RDark
linenumbers	true

if (isset($_SERVER['PANTHEON_ENVIRONMENT'])) {
  if($_SERVER['PANTHEON_ENVIRONMENT'] === 'live') {
    // settings for launching Featured Events
    if($_SERVER['HTTP_HOST'] == 'live-mysite.gotpantheon.com' || $_SERVER['HTTP_HOST'] == 'www.mysite.com'){
      header('HTTP/1.0 301 Moved Permanently');
      header('Location: http://mysite.com'. $_SERVER['REQUEST_URI']);
      exit();
    }
  }
}
