There is nothing wrong with Delphi 7 for applications today, if anything they are less bloated than later compilers where EXEs just get bigger with no extra functionality, All my ICS development and commercial applications are Delphi 2007, but then tested and made compatible with the latest and greatest of the day.  Obviously cross platform development is another matter, but I don't do that.  And lots of new language features and library functions, which ICS seems to manage without, or has implemented it's own versions to be compatible across all compilers D7 up. 

 

For client/server, also look at the new ICS component TIcsIpStrmLog and sample OverbyteIcsIpStmLogTst, the component can be configured as TCP/UDP/Client/Server with SSL/TLS, and mainly just sends lines of text back and forward, with two methods to connect/listen and send and one event to receive, you can build client/server apps very quickly.

Thanks for suggestions, I'll definitely try the component that you mentioned.

Websockets are designed for use in browsers, as a more efficient duplex mechanism than Ajax, for interactive content like spell check and auto completion as you type.  

 

Don't see any purpose outside the browser environment where simple TCP client/server has been used for 30 years.  ICS has several sockets demos illustrating various client/server concepts.

I'd add that sometimes UDP more reliable in some configuration eg. when a client is behind a router connecting to outer world. But the source of my question is heterogeneity of clients in my specific client/server configuration: Android App, Delphi 7 App, Web browser. It's kind of monitoring system having various UIs watching changes. Of course it's possible to implement 3 different approaches of data exchange but I'd like to use uniform. So my concern is still one of 3 options: HTTP polling, Web sockets or mix of UDP/HTTP. Obviously, I'd never use Delphi 7 as a backend but it's a requirement of the legacy system.

Ideally, websockets should be integrated into the ICS web server so they can be used on the same ports, the request that starts them up is HTTP, and I'll do that is anyone needs it.

It would be great.

As far as I got this example is just a websockets server implementation. I did not understand how to build a websockets client (not javascript but Delphi).

Could you clarify what is the websockets test environment?

I will do a quick evaluation of building that old code with the latest ICS over the next few days, but I won't do anything further unless someone else sets up a websockets test environment to test it all, that often takes as long as the coding, a server and client that the ICS components can be separately tested against.

Dear authors and community.

I'd like to use Websockets using ICS library. I know it's not a part of the library but probably someone could share his own implementation or may be has already found in the internet.

Thanks in advance.
