Why should I make a copy of a context for goroutines inside handlers?

Issue

This Content is from Stack Overflow. Question asked by Michael

I recently started rewriting some of my Python services in Go to speed them up and came across this section of the gin documentation:
https://github.com/gin-gonic/gin#goroutines-inside-a-middleware

So I understand the instructions, but I’m trying to understand why? What is the significance of making a copy, and what problem is introduced if I do not make a copy of context for goroutines within handlers?
