I don’t understand this. Let us suppose my website server is in Seoul. When I post a new link in my website (which is behind Cloudflare), which edge server or location has the post firstly? I mean: if everybody in all cities in the world makes a HTTP request at the same time just when I post the link, who has the new post firstly? How does that process work?
Thank you
In your example if everyone in all cities in the world were to request your website at the same time, and the result was not previously cached, then I believe that the request closest to your origin server would most likely be the first one to get the response. This is because when the requested asset is not in cache, your origin must be contacted directly to retrieve the asset. After this request, the asset would now be in cache globally, assuming that it is cacheable.
