Web Caching
Explore the fundamentals of web caching and understand how it minimizes database latency by storing data at various points between clients and servers. Learn about caching benefits, including improved responsiveness and load handling, and discover practical caching tools like MongoDB, Redis, CouchDB, and Memcached for efficient web development.
We'll cover the following...
In the previous lesson, we discussed the latency that frequent database calls introduce in web applications. Now, we will look into web caching as a means of eliminating this latency.
Introduction to web caching #
Web caching is a design feature of the HTTP protocol that is meant to minimize the amount of traffic an application is handling at any given point in order to improve the responsiveness of the web application, as perceived by users, as a whole. In order to do this, caches are used at each level starting from the server itself all the way to users’ browsers, and each of them is meant to store data that users are very likely to request.
Essentially, web caching works by ...
