HTML caching in OpenCart online stores using the IMCache module

HTML caching in OpenCart online stores is quite a typical task, since this action helps to improve the website’s ranking in search engines (better PageSpeed metrics and, in general, users enjoy faster speed).

What are the main problems that need to be solved when caching HTML?

1. Actually, caching of standard OpenCart pages (products, categories, manufacturers, search, homepage)

2. Ensuring that when a product changes, there is no need to manually clear the cache and that it is recreated automatically. For example, if products are updated and the price changes, the cache should track this so that prices remain up to date. Another example – if a product goes out of stock, the cache should be automatically rebuilt

These two tasks are exactly what the IMCache module solves

Firstly, the module can cache the main OpenCart pages.

Secondly, the module monitors product price changes, special price changes, edit date changes, as well as stock changes (from positive to 0 or negative and vice versa).

And this is done very easily. After installing the IMCache module – you just need to enable it, as shown in the picture below

Another useful feature is that you can configure the caching time for each type of page. For example, set one month for products. The module has special convenient buttons for quick setup. Remember to save the settings after making changes.

Finally, I’d like to add that caching is great, but you should always keep in mind overall website optimization. On this topic, I also recommend checking out the IMDBOptimizer module and reading the review https://liveopencart.ru/tips/sovety-po-optimizatsii-opencart-o-kotoryh-stoit-znat-kazhdomu/
