Single server checking multiple client simultaneously - How to?

[canavaroski90]

Hi,

Now I have 2 new questions.

1. If I get same response from all clients and if I send 6 independent iport/path request, how can I know that which response belongs to which client? And if any of the clients not reply (i mean reply returns with error code), then how can i know which one of them has not replied?

2. Could you please give more detail about iport pair? Assume that there is 1 QNetworkAccessManager, so does it mean I can send 6 request in total or 6 request per ip-port pair?
ie.
lets say there is 4 different ip-port pairs
1.2.3.4:80
1.2.3.4:81
1.2.3.5:80
1.2.3.6:80
consider the first 2 pair: can i send 6 seperate and simultaneous request per pair? that means i can send 6 request per port hence ip address doesn't effect the limitation of requests. Considering the all pairs, can i send 24 simutaneous and seperated request with just 1 QNetworkAccessManager?

thanks

Each request is handled by its own QNetworkReply instance. It contains the QNetworkRequest object that was used to initiate the operation, even has a convenience accessor for the URL.

And if any of the clients not reply (i mean reply returns with error code), then how can i know which one of them has not replied?

Those for which you have not gotten the finished() signal. If you want to impose some timeout, do that with a timer.

2. Could you please give more detail about iport pair? Assume that there is 1 QNetworkAccessManager, so does it mean I can send 6 request in total or 6 request per ip-port pair?

6 per pair, any number if you have different pairs.

Considering the all pairs, can i send 24 simutaneous and seperated request with just 1 QNetworkAccessManager?

Yes, I think you can.
