# Game Content Cache Hostnames

## Introduction

This is a list of all hostnames that are required to be redirected for running a game content cache. This list will change frequently so this is designed to be a definitive list.

## Usage

You can use this list one of two ways:

 - Overriding DNS for these hostnames to point to the IP of your cache server.
 - Use them in Squid with WCCP to redirect content to the right cache server.

There is a cache_domains.json file to define CDNs and additional meta deta with the following structure

- cache_domains: Array of cache_domain object
	- name: shortname for the cache domain
	- description: a longer description to aid others in identifying what this domain does (not all users of this repo will want to enable all caches)
	- notes: implementation specific notes which may be useful for other users
	- mixed_content: true if this domain hosts mixed https and http content (a straight dns injection is unlikely to work in this case). Assumed to be false if undefined
	- domain_files: array of files within the repo assosciated to the cdn. Most cdn's only need one file
	- Example domain entry for origin
```json
{
	"cache_domains": [
		{
			"name": "origin",
			"description": "CDN for origin",
			"notes": "Should be enabled for HTTP traffic only or with a HTTPS proxy else origin client download fails",
			"mixed_content": true,
			"domain_files": ["origin.txt"]
		}
	]
}
```

There is a separate file for each cacheable service. Some notes on formatting:

  - Every line should be a seperate hostname for that service.
  - Wildcards can be represented with an asterix.
  - Only one wildcard is permitted per line.
  - If a wildcard is used, it should be the first character on the line.
  - Wildcards are not treated as matching null, e.g. `*.example.com` will match `a.example.com` but will not match `example.com`
  - Lines starting with a # will be treated as a comment.
  - Files must end with an empty newline.

## Updates

Please fork this repository and submit pull requests if you have any extra hostnames or services to add. We want this list to be definitive and collaborative!

### New CDNs

If the CDN you are adding does not already exist please remember to add an entry within cache_domains.json as well as a new .txt file
