What is the cache?

If you have worked with web projects, it has surely happened to you that you want

"insurance is cache, cool your browser and check again"

but in reality, what is the cache?

The purpose of this memory is that these frequent access data are more quickly display /span>

think of the page that you like, the one you enter more frequently. What your browser does is that the first time you enter that page, keep all the relevant data, images, texts, files, etc.  So that when you enter again, you do not have to bring all the data again but show you what you have already kept, the times following your first visit, that site will load much faster.

in summary, cache is a temporary memory of fast access data . the main problem related to cache is not visualizing updated content and continuing to see the previous ones. This causes confusion when validating changes that have been made over the course of a day, mainly to developers or people who manage or validate content of web sites or applications.

the best way to avoid these problems is to configure the browser from which the reviews are made so that it does not keep cache, or, every time it will be done The review of a frequently visited site is recommended to erase the browser cache before r In Mac. Although you can also do it from the browser configuration, here I leave you a post where we indicate step by step how to do it in different browsers.

another option to avoid this problem, especially in mobiles, is to navigate in private mode. Currently browsers already allow navigating sites in private or unknown mode, the advantage in this way is that it does not keep cache, which facilitates the reviews you should perform.
