Socket transport for long poll clients.

Configuration

The long poll is configurable in your socket:

transport :longpoll, Phoenix.Transports.LongPoll,
  window_ms: 10_000,
  pubsub_timeout_ms: 2_000,
  transport_log: false,
  crypto: [max_age: 1209600]

• :window_ms - how long the client can wait for new messages in its poll request

• :pubsub_timeout_ms - how long a request can wait for the pubsub layer to respond

• :crypto - options for verifying and signing the token, accepted by Phoenix.Token. By default tokens are valid for 2 weeks

• :transport_log - if the transport layer itself should log and, if so, the level

• :check_origin - if we should check the origin of requests when the origin header is present. It defaults to true and, in such cases, it will check against the host value in YourApp.Endpoint.config(:url)[:host]. It may be set to false (not recommended) or to a list of explicitly allowed origins

• :code_reloader - optionally override the default :code_reloader value from the socket’s endpoint
