Introduction
It is my favorite article to read, and I spent over an hour to read.
Reading is fastest way to learn
I like to ask questions, and also read out loud, so that I can understand the topic better.
Here is the article.
two general approaches: client pull or server push.
A few ways to implement these:
- Long/short polling (client pull)
- WebSockets (server push)
- Server-Sent Events (server push)
Actionable Items
I also like to write down my thought process. I still remembered that I failed onsite interview question from Fortinet this May 2019, if a web page has submit button, what happen if the button is clicked twice quickly?
I really like to read more carefully, and most important I should pay attention to those terms, ajax polling, long term polling, and what is TCP and how many connections stay open?
