Hi Mkykadir,

Thanks for the contribution!

Its a clever solution, however I am concerned about a race condition occurring with concurrent map access w.reqIdToMethod if the proxyd was under heavy ws traffic.

I'm curious if you would be able to find a solution that can avoid this?

Also please include test cases if possible

In the PRs current state with concurrent map access, I believe these concerns must be addressed before merging

@jelias2 nice catches actually I missed a crucial point as well:

• reqId within context is determined on WS connection and shouldn't be used for all following ws messages
• now each ws connection will have its own concurrent map
• and following message ids will be used for this
• after its ok for you I'll go with tests as well
