Web Sockets

Web Socket Server and Client implemented in C# and Clarion for the modern version 13 of the WebSocket protocol.

Based on CodeProject's article WebSocket Server in C#.

WebSocket server

• SSL support

WebSocket client

• can be written in Clarion, JavaScript, and so on.
• untrusted connections allowed

Real chat server and client ("webchat" folder).

• Server: default port 88. To change this behaviour, edit ChatServer.INI.
  Copy WebSockets.dll file from \BIN into CharServer folder before running the server.
• Client: if a server is running on same machine, client's app can connect to that server using "localhost": ws://localhost:88/chat. (In my home network I can use ws://192.168.1.2:88/chat host address.) Copy WebSockets.dll, EasyHtml.dll files from \BIN into CharClient folder before running the client.

How to test:

• Start TestServer.exe. To enable SSL, set following INI settings: port=443
  certfile=mycert.pfx
  certpwd=mypassword

for web "chat" client:

• Open http://localhost:88/client.html page (or https://localhost/wssclient.html if SSL enabled) in web browser, file TestServer\web\client.html will be loaded;
• type something in entry field and press "Send". A text you typed in will be send to the server, server will send it back to the client in upper case; you'll see the response in web browser.

for Clarion "chat" client:

• run TestClientSrc.exe;
• press "Connect" to connect to the server;
• send some text, server will send it back to the client in upper case;
• send a file, server will inform about file received.

for Clarion "people" client:

• run people.exe (standard app from Clarion examples);
• run another copy of people.exe from different folder (so that 2 exe copies will connect to 2 different databases PEOPLE.TPS);
• open People browse in each running copies;
• Make database changes in one of people app (insert, update or delete records). You will see a message in another running app, that there is pending changes, and you're able to synchronize 2 databases. Under the hood: first "people" client sends db changes to the server, the server sends these changes to all other "people" clients.
