谈论HTTP请求时，Go lang中的CONTEXT是什么？

Question

To some this might be a stupid question. On the other hand this is is very important to me. I am new to Go programming and when I read this Sharing values between Middlewares and this Go Concurrency Patterns: Context I could not figure out what exactly what they meant by Context when referring to sharing values between middleware handlers or request handlers in general.

I've been able to write a web framework with Go -- Frodo. Not perfect in a lot of ways, it was a learning experiment. As you see I am not stupid. Just under informed being new to Go lang.

Thank you in advance for a comprehensive explanation.

I found a great explanation at the beginning of this blog: HTTP Request Contexts & Go

Request contexts, for those new to the terminology, are typically a way to pass data alongside a HTTP request as it is processed by handlers (or middleware) you have written. This data could be a user ID, a CSRF token, a web token, whether a user is logged in or not—something typically derived from logic that you don't want to repeat over-and-over again in every handler. If you've ever used Django, the request context is synonymous with the request.META dictionary.
