Restricted CMS
==============

[](#restricted-cms)

> A SilverStripe CMS module that will force users to a different hostname when hitting protected URLs.

Requirements
------------

[](#requirements)

- SilverStripe 3.2.x

Getting Started
---------------

[](#getting-started)

- Place the module under your root project directory.
- `/dev/build`
- Create a restrictedcms.yml file in your project \_config/ folder, with config similar to that found in docs/en/restrictedcms.yml.sample

Overview
--------

[](#overview)

The restricted CMS module works by intercepting incoming requests to the CMS and comparing them against a set of patterns for particular hosts, to determine whether they should be allowed to be served by the current server.

This provides two layers of protection

- Verifying the HTTP\_HOST presented by the end user is allowed to be served by 'this' server
- Allowing requests to particular URLs to be redirected to different hostnames, which in turn may be behind a firewall somewhere.

Specific environment configuration
----------------------------------

[](#specific-environment-configuration)

If you have a separate authoring instance (ie cms.mysite.com) to your main site (eg [www.mysite.com](http://www.mysite.com)), you can specify configuration that is loaded just for the specific environment. Using the sample restrictedcms.yml.sample file, the config blocks for each environment can be included / excluded by making use of the ENV\_TYPE\_FRONTEND or ENV\_TYPE\_BACKEND defines from your \_ss\_environment.php in the respective environments.

As SilverStripe's configuration layer only allows the swapping based on `define`d properties, you may need a fragment like the following if you're setting these properties via environment variables from your webserver

```
foreach (array('ENV_PROD', 'ENV_TEST', 'ENV_TYPE_FRONTEND', 'ENV_TYPE_BACKEND') as $envVar) {
    if (getenv($envVar)) {
        define($envVar, 1);
    }
}

```
