[8] [9] The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not consuming resources to run multiple server processes or threads for too ...

WAMP requires [6] a reliable, ordered, full-duplex message channel as a transport layer, and by default uses Websocket.However, implementations can use other transports matching these characteristics and communicate with WAMP over e.g. raw sockets, [7] Unix sockets, or HTTP long poll.
Because of this, only HEAD and some GET requests (i.e. limited to real file requests and so with URLs without query string used as a command, etc.) could be pipelined in a safe and idempotent mode.
