WebSocket server implementations for Delphi

Question

As mentioned on the Aquarium, the WebSocket protocol, often described as one of the key elements of HTML5, has finally been blessed (RFC 6455).

Which WebSocket server implementations are available for Delphi?

• Delphi on Rails (Google Code, Mozilla Public License 1.1)
• Delphi Web Socket (Google Code, based on Indy 9, New BSD License)
• WebSockets Delphi Components (commercial, Indy 10, Delphi 7 to Rio)

Solution 1

Newer version of Indy implementation by André Mussche (the author of AsmProfiler) can be found here.

Solution 2

It is implemented in Delphi on Rails, it support old and new WS protocol. http://code.google.com/p/delphionrails/

Solution 3

Here is 2 more projects:

• bauglir-websocket - WebSocket server/client implementation in Pascal and C#;
• ics-websockets - WebSockets server for Delphi based on Internet Component Suite (ICS);

Solution 4

Try IPworks for Delphi, they have nice quite of interoperable components (paid, not free).

The WServer component docs does not make clear if it is possible to use the same port (80) both for normal HTTP and Websockets. Do you know if this is supported by their library?

[Rick Wheeler]

I currently use their SSL component for HTTP & HTTPS on 80/443 respectively. However I'm still evaluating their WS component so I cannot give you an answer just yet. Perhaps try their support email, I've always found them to respond quickly and professionally.

You can use the LocalPort property in the WSServer component. So assuming you don't already have something listening on port 80, you can set LocalPort to 80 and the component will listen on port 80. As Rick mentioned, feel free to email [email protected], we will get back to you within 24 hours (usually better).

Also the link Rick posted is no longer available you can still access the information from nsoftware.com/ipworks/ws/#plat-delphi.

For anyone coming across this answer, you may notice that André has stopped work on his implementation. Chee Wee Chua is pretty active in his fork: github.com/chuacw/WebSockets
