[Edge Functions] Are Websocket connections terminated after the maximum duration, wall clock limit? (150/400secs)

[tomtitherington]

I was reading the docs here and was wondering how to interpret the limits in the context of Websockets with Edge Functions. Specifically the docs state:

Maximum Duration (Wall clock limit): This is the duration an Edge Function worker will stay active. During this period, a worker can serve multiple requests or process background tasks.
Free plan: 150s
Paid plans: 400s

Does this limit refer to the duration of the initial HTTP upgrade request (before the socket is opened)? Or is this limit imposed on the entire Websocket connection?

I believe they would have to be as the entire edge function gets shut down.
From the Edge function websocket docs.

Yes, the duration would start from the time the Edge Function processes the initial HTTP upgrade request (ie. when the function booted)
