I want to close it explicitly when it is no longer needed

[miha-x64]

Returning from suspend function closes WS, AFAIK.

[noncom]

yeah, but that's weird... why would I want to do this?

[noncom]

websockets are not AJAX.. they are meant to be persistent

[noncom]

maybe I just don't understand how to use the mechanism properly

[noncom]

I would be grateful for a hint on how to manage this situation properly

[miha-x64]

Suspend function invocation may long several hours/days, it's OK. You can use delay() and many other non-blocking (suspending) waiting mechanisms.

@miha-x64 could you please elaborate on what would be the best way to suspend the execution of the websocket invocation while I save the session and use it from elsewhere?

[noncom]

I can imagine creating some kind of a lock, like a boolean value to indicate from elsewhere that the websocket can be released, and in wait for it inside the websocket routine...

[noncom]

but I'm not sure what would be the best choice for the waiting mechanism here...

[miha-x64]

You can use low-level coroutines API to manually suspend/resume function. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.coroutines.experimental/suspend-coroutine.html

I highly recommend you watching Roman Elizarov's talk about coroutines:
