How do I serialize DefaultWebSocketServerSession ?

[Deactivated User]

What’s your use case? What are you trying to achieve?

[aeruhxi]

store it in redis

[Deactivated User]

But that session is a wrapped socket connection, that won’t exists later. You cannot serialize a socket

[Deactivated User]

what you can do is to serialize a state that you associate to that session

[Deactivated User]

you can use jackson or gson to serialize/deserialize a simple data class with your state, but not with a socket

[aeruhxi]

If I have ktor on multiple instances, how do I share websocket sessions?

[Deactivated User]

usually you have a session, you can store it on redis if you want

[Deactivated User]

Here there is a proposal for redis sessions: https://github.com/ktorio/ktor/pull/504/files

You can copy the code and use the redis client you are using for it

[Deactivated User]

As long as the client has the same session-id, if it reconnects to another server, that redis-backed session should work

[Deactivated User]

if you want the state to be associated to the user instead to a session

[Deactivated User]

you can use raw redis to do that

[Deactivated User]

for example: hset("props-$userId", "property", "value")
