Java Websockets Development
Raj P. Malhotra · Apress eBooks · 2019
This chapter covers how to use Websockets in Java to create real-time applications supporting millions of concurrent users. Websockets provide a bidirectional persistent connection to a HTTP web server so that the time taken to create HTTP connections can be reduced. HTTP 1.1 also allows long-lived connections through the keep-alive header, but the payload in each request is significantly bigger than Websockets.
