Introduction

qcacher is a service designed for long-term caching of various content networks related to gaming. It is designed not only to maximize efficiency of fast connections with multiple clients, but also deliver long-term reliability and resiliency of caching when paired with slow, or intermittent connections.

Supported services

We currently support content caching and delivery for the following services:

• PlayStation Network (PS3 & PS4)
• Xbox Live (untested)
• Nintendo (3DS & Wii U)
• Blizzard (Starcraft 2, Hearthstone, etc.)
• Riot (League of Legends)
• Steam (Broadcasts, Games, etc.)
• Origin (EA)
• Hi-Rez (Smite, etc.)
• PlanetSide 2
• Twitch.tv
• Microsoft Windows updates
• NVIDIA driver updates
• Mozilla Firefox

Components

There are 3 components to this service:

• nginx - a fast, lightweight, and efficient web server configured to cache and store content from supported delivery networks
• unbound - a flexible and fast DNS server configured to override records of the services we support
• sniproxy - proxies incoming HTTPS and TLS connections to overridden domains to ensure successful connections to the upstream service

Getting Started

NOTE: This section is still incomplete. A simple tutorial will be available in the coming weeks.

Running the application

To get started with this application you will require docker and docker-compose. If you don't have these tools installed please see the section of installing them.

Further documentation and configurability is pending, but configure the DNS_IP in docker-compose.yml to that of your host, and have clients use the running machine as a DNS server.

Once you have Docker installed and the IP configured, it is a as simple as running docker-compose up in the root of the repository to start all the required services.
