This specification defines a WebSocket extension that adds per-frame compression functionality to the WebSocket Protocol. It compresses the "Application data" portion of WebSocket data frames using specified compression algorithm. One reserved bit RSV1 in the WebSocket frame header is allocated to control application of compression for each frame. This specification provides one compression method available for the extension using DEFLATE. Please send feedback to the mailing list.
