| How to create a "TCP/IP relay" server? |
|

I am using Indy in a server for handling external equipment which is monitoring dams and waste dumps for leakage.
This system might be powered by solar cells on very remote locations.
The server has been ported from Delphi on Windows to FreePascal on Linux and runs on a RaspberryPi4 device.
The old client on Windows works also with this new server but to accommodate the differences between Windows and Linux I have had to also port the client application to FreePascal/Lazarus and add Unix/Windows difference handling.
When doing this I have replaced the "native" Delphi TCP/IP components with Indy server and client objects in both applications.
So now (almost) everything is running as intended but I have run up against a connectivity problem...
When the system is deployed it will use a mobile broadband connection to the Internet and I have found that the way these are done today often (always?) do not include for the router to get a public IP address so that one can use DDNS to find the address and connect to the server on RPi4 for configuration, monitoring and data download.
So now I wonder if there is a way to use Indy to make some kind of "relaying server" that could run on a Linux box with public IP to which the RPi4 remote server can connect and to which our client could also connect and specify which system it wants to talk to, whereupon the relaying server channels all traffic from the client over to the connected remote server and vice versa (if it is actually connected) so that both can start talking to each other using our already established specific protocol?
I don't know what this kind of operation could be called so it is hard to google, I hope you get the idea anyway...

Hello!
Do You know if it is possible to complie IW 15.0.21
for Delphi 10.4.2?
We have some compatibility issue with 15.2.25 and the new one seems to be
slow even with a small test project. (1.7ms vs 380ms).
(with CGDevTools)
Best Regards:

I migrated one of the intraweb application from Version 14.2.1(Delphi 10.2) to 15.2.27(Delphi 10.4.2). Successfully compiled and pages are working properly but one thing noticed is asynchronous click event is not working properly. When click event is fired but nothing is happening but some times it will work after a second or third click on few buttons. Any changes is required in 15.2 please? It is working properly in the 14.2

Hello,
is there a simple example how to use callback functions whithin c++.
I think it’s more complex to define as in the delphi example.
I tried this:
void TfrmMain::myCallbackMethod(TStringList *slList)
{
// some Code
}
void __fastcall TfrmMain::headerRightButtonClick(TObject *Sender)
{
WebApplication->RegisterCallBack("MyCallback", &myCallbackMethod);
}
but it doesn’t compile.
Any hints?
