    \brief Show how to write a simple WebSocket server application.

    This Echo Server shows how to create a simple server application that sends
    back a reply in response to a message it receives, using the
    \l {Qt WebSockets}{WebSocket} API. For the sake of illustration, the reply
    is simply a copy of the message.

    If your web browser supports \l {Qt WebSockets}{WebSocket}, you can also use it
    to open the \c {echoserver/echoclient.html}{echoclient.html} file, and operate
    as shown in the following screenshot:

    Otherwise use the \l {WebSocket Echo Client} to connect to the server.

    \sa {WebSocket Echo Client}
