The mod_websocket module is an Apache 2.x server module that may be used to process requests using the WebSocket protocol (RFC 6455) by an Apache 2.x server. The module consists of a plugin architecture for handling WebSocket messaging. Doing so does not require any knowledge of internal Apache structures.
This implementation supports protocol versions 7, 8, and 13, along with the older draft-76 of the WebSocket protocol. Support for draft-75 is disabled by default, but it may be enabled through the draft-76 module configuration. Although draft-76 is technically obsolete, it is the protocol version that is currently implemented by most of the web browsers. When all of the browsers finally move to support the latest protocol, simply remove the draft-76 module and configuration to drop support.
