How to tell who disconnect ws?

Hi @uNetworkingAB

Thank you for your project!

I want to know how to tell who disconnect ws in .close? Server or client?

In .close = [this](auto *ws, int code, std::string_view message) {
I can only get code, but the value 1000 can not identify the one who disconnect.

Thank you.

Code 1006 is reserved for the library. It cannot be sent over the wire so getting that code in close handler means it originated from the library itself.

Thank you for your reply!

It means if I got a 1000, then the connection is closed by client?

Thank you!

Yes and you can also see this if you look at WireShark or similar tcpdump

Hi @uNetworkingAB

I got a 1006, maybe this is caused by fire wall or VPN.

How to prove this?(ws is closed by client side fire wall or VPN)

Thank you!
