PUT vs POST: What's the difference?

Ever wonder what the difference was between PUT and POST methods of the HTTP protocol? It's something every RESTful web developer must know.
These purpose of the two PUT and POST HTTP verbs are similar, but there are significant differences that pertain to payload, URLs, idempotence and the types of operations PUT and POST methods are allowed to perform.
This quick tutorial on POST versus PUT methods of the HTTP protocol will help you understand the difference between the two, but it will also help you understand the history that led up to the creation of the various HTTP methods we commonly use today in the RESTful web services and microservices we create today.

Thanks for your kind words!
I worry it's too technical. But I also feel so many tutorials on the topic gloss over the nuance of POST vs PUT and actually get a lot of the concepts wrong.
Thanks for watching!
