[BUG] If `deadline` argument to `WriteControl` is `deadline.IsZero()` then 1000 hours (~41 days) are used as unexpected and undocumented fallback about websocket HOT 2 CLOSED

Champion @JannikGM thank you. I'm taking a look at this now.

from websocket.

Nothing in the RFC seems to indicate any sane value for this. I don't know of any websocket extensions that need to be accounted for in any changes here.

It appears to me that this code is used in both client and server connections, so this probably is a more important function when it comes to clients being unable to write to the server.

Based on that information I think that the following actions should be taken:

1. The default is documented as a warning
2. Any examples should be updated to include setting this deadline to a sane standard
3. This issue should be left open and marked for a v2 as changing this could be a nasty surprise for implementors that don't know about this
