Master the art of caching in OpenCart

Master the art of caching in OpenCart

Nowadays, if you are dealing with a global audience, you cannot go offline for even a few minutes as it will give your competitors a chance to prove they are ahead of you.

It really helps relieve the web server of the heavy lifting required to handle thousands (or even millions) of requests simultaneously. There are many options available today to improve the performance of your web application, but the basic concept of caching remains the same. Gone are the days when you could simply build a static HTML website with a few pages to accomplish the purpose of caching. In this case, you don't have to worry about concurrent requests and a lot of traffic generated on your website because sending these static pages is easier than dynamic web pages that require a lot of server resources to build.
