Question regarding the KeepAliveIntervalMs parameter

[tldQuantic]

Hi,
I have a question regarding how to detect all types of disconnection between client<->server.

There are especially two cases that I want to detect:
1- From the client point of view, I want to be notified when the server crash or is killed by the user.
2- From the server point of view, I want to be notified when the client crash or is killed by the user.

On client side, I added this parameter:
settings.KeepAliveIntervalMs = _uiKeepAliveIntervalMs;
settings.IsSet.KeepAliveIntervalMs = TRUE;

So, now, if the server crash, the client will be notified by MsQuic callback depending of the KeepAliveIntervalMs value and when the DisconnectTimeoutMs is reach.

The problem is that I can't do the same thing on server side.

According to this documentation:
https://github.com/microsoft/msquic/blob/9d5574187b6d9b14ae3a47dba1cd5e7b1b5e2b27/docs/Deployment.md
"They can be enabled on either the client or server side, but only need to be enabled on one side. They can be enabled either dynamically in the code or globally via the settings. To enable keep alives via the settings, set the KeepAliveIntervalMs setting to a reasonable value, such as 20000 (20 seconds)."

If I try to enable this parameter on both side, this will have the same behaviour as the IdleTimeoutMs parameter and that is not what i want.

So, I am wondering if I missed something somewhere :)
Any help will be appreciated !

Why are you saying you get the same behavior as IdleTimeoutMs in this case? You should just have keep alives polling on both sides.

Hi,
I made the test again by enabling the KeepAliveIntervalMs parameters on both side.
I don't know what I did wrong previously but now everything is working fine !
Sorry for the inconvenience.
Thanks
