gun - Erlang HTTP client with support for HTTP/1.1, SPDY and Websocket.

The gun application uses the Erlang applications ranch for abstracting TCP and TLS over a common interface, and the ssl application for TLS support, required for HTTPS and SPDY support. In addition, Gun requires the crypto application (a dependency of ssl) for Websocket.

These dependencies must be started for the gun application to work. In an embedded environment this means that they need to be started with the application:start/{1,2} function before the gun application is started.

The gun application does not define any application environment configuration parameters.
