Specifying Sec-WebSocket -Protocol forwebsocket connection
EugeneK posted a topic in ICS - Internet Component Suite
Hi Some protocols require Sec-WebSocket -Protocol header to be set when connecting, I made a patch to allow it in OverbyteIcsWebSocketCli.pas OverbyteIcsWebSocketCli.pas.patch -
WSSendBinaryStream usage
Angus Robertson replied to sfrazor's topic in ICS - Internet Component Suite
I've added a new event OnWSFramesDone to theWebsocket client, called when the queue of frames has been sent, for flow control when sending a lot of data. Previously, the OnWSFreameSent was called after each frame, but it was not easy to tell if this was the last queued frame. I've onl... -

There is also ICS Application Monitor - Remote Manager application that provides remote monitoring of multiple ICS A...

WSSendBinaryStream usage
Angus Robertson replied to sfrazor's topic in ICS - Internet Component Suite
...I gather you are writing aWebsocket client DLL that sends large binary blocks of data to a server, All my testing and the ICS samples are server to client communication, although in theory the code is two-way and similar in client and server. But I simply don't have a way to easily test your requ... -

Websocket client and server configuration issue
FrozenK posted a topic in ICS - Internet Component Suite
...I'm trying to configure the most simplewebsocket client (with TSslWebSocketCli) and server (with TSslHttpAppSrv) in order to get them communicate with each other locally. Worth noting that I'm a beginner in the internet communication protocol world, this is why I'm trying to get the minimum... -
...I wish to useWebSockets with ICS Delphi components. I wish to use this in a very large and important system (cannot name it). I am challenged to prototype this because the Overbyte demo OverbyteIcsSslMultiWebServ.dpr has so many features it is impossible to extract a simplewebSocket ser...

Websocket client and server configuration issue
Angus Robertson replied to FrozenK's topic in ICS - Internet Component Suite
...Your settings are missing awebsocket path or page, just ws://127.0.0.1/ so you are assuming the web server default HTML page is actually aWebsocket request, this was never testing with the ICS web server, perhaps my fault for not expecting anyone to try that. Since you set default pa... -
...So I want to offer aWebsocket API as well, so one SSL/TLS session stays open, with just simple request/response packets sent. But how to adapt the REST HTTP request/response toWebsocket ? My queries are simple URL parameters, ie codelookapi.htm?numhistory=118118....

...But this sample will be a much easier starting point for those developing web orWebsocket servers with ICS. I'm going to copy most of the code into another new ICS sample that needs aWebsocket server. Angus

Retrieve Json frame
Angus Robertson replied to CoeurdeLeon's topic in ICS - Internet Component Suite
If you really mean thewebsocket protocol and not HTTP, there are no header or bodies or protocol, once awebsocket is open there is simply a two way TCP stream, and you can send what you like. That stream arrives at the server in the ClientWSFrameRcvdEvent as a string packet and TWebSo... -
The OverbyteIcsSslMultiWebServ sample serves both web andwebsocket pages, since allwebsocket requests start with an HTTP request to port 80/443. But you can remove all the code relating to creating web pages from the sample, the OverbyteIcsSslMultiWebxx units, etc, leaving just the def...

ISC 9.1 as a library events not firing
sfrazor replied to sfrazor's topic in ICS - Internet Component Suite
Angus Using TSslWebSocketCli, after setting CertifyMethod to CertVerNone, verifypeer no longer gets executed. But theWebsocket connects and is ready. If it completely bypasses all internal chain verification AND does not fire verifypeer (which it seems to behave the way you described), how d... -

Angus Robertson replied to sfrazor's topic in ICS - Internet Component Suite
...If you are using the realWebSocket protocol, it exchanges frames between client and server, and vice versa, and there are several methods WSSendText, WSSendBinary, WSSendFrame, etc, with the OnWSFrameRcvd event being received frames, which you need to check the data type and then proc... -
ISC 9.1 as a library events not firing
Angus Robertson replied to sfrazor's topic in ICS - Internet Component Suite
The purpose of theWebsocket is to exchange data with a server, so it opens a connection and does a GET to the path you specify, just as HTTP does, if you don't want that it's notWebsockets . I suggest you try using the OverbyteIcsHttpRestTst sample I mentioned, if that does not work you... -
ISC 9.1 as a library events not firing
sfrazor replied to sfrazor's topic in ICS - Internet Component Suite
...YesWebsocket as a protocol. I understand that. I was originally using OverByteSimpleSslCli as an example reference and it uses TSslWSocket and TSslContext and it seemed like a great starting point. So I just now switched to TSslWebSocketCli and can do a little refactoring. But in regards to... -

Angus Robertson replied to sfrazor's topic in ICS - Internet Component Suite
...Websocket is a specific protocol based on HTTP. TWSocket is the name of the base ICS component for all low level socket operations, and does not handle high level protocols likeWebsocket . ICS has a TSslWebSocketCli component, there is a simple function doWebSocketClick in the Overbyte... -

Designing aWebsocket API
Angus Robertson replied to Angus Robertson's topic in ICS - Internet Component Suite
The newWebsocket API is live, when using streamlined requests, it handles about 100 SQL queries a minute from a single thread, although slower if the requests are sent sequentially waiting for a reply. Supporting JSON-RPC 2.0 on the server should not be hard, but does need POST support...
