Once the handshake phase has been completed, all the data the client sends will simply be reflected (echoed) back at it. Netty has been designed carefully with the experiences learned from the implementation of a lot of protocols such as FTP, SMTP, HTTP, and various binary and text-based legacy protocols. The API has seen a few changes, one of them is the API is now fully asynchronous. Ease of use: Netty is simpler to use than plain Java NIO and has an extensive set of examples covering most . In other words, it won't close the connection until the client closes it, and can receive additional HTTP requests over the same connection? build (); The API is callback-based. First, we need to include a dependency in our pom.xml that's responsible for running an embedded server during the application startup. Netty Creating an interactive web site.
