This page is most useful when loaded from localhost.
You should first create a server using the <a href="http://tests/server">HTTP/WebSocket Server test</a>.
</div>
<p>
This page tests a WebSocket connection.
The example implementation in server_test.cc will then echo the message contents in reverse.

<form>
Server URL: <input type="text" id="server" value="" disabled="true">
<br/><input type="button" id="connect" onclick="doConnect()" value="Connect" disabled="true">
<input type="button" id="disconnect" onclick="doDisconnect()" value="Disconnect" disabled="true">
<br/>Message: <input type="text" id="message" value="Test Message" disabled="true">
<input type="button" id="send" onclick="doSend()" value="Send" disabled="true">
<br/>Response: <input type="text" id="response" value="" disabled="true">

The example implementation in server_test.cc can also serve the HTTP-based <a href="other_tests">Other Tests</a>.
