NetTus.com has followed up their previous article covering some of the basics of the HTTP protocol with this new post, part 2 of the series. They suggest that HTTP, the messaging format of the web, is the one protocol that every web developer should know.

In my previous article, we covered some of HTTP’s basics, such as the URL scheme, status codes and request/response headers. With that as our foundation, we will look at the finer aspects of HTTP, like connection handling, authentication and HTTP caching. These topics are fairly extensive, but we’ll cover the most important bits.

In this article, they talk about things like the HTTPS secure version of HTTP, server-side connection handling, identification/authorization and working with caching and cache control headers.
