Back in the “old days,” before high-speed Internet and WIFI, everyone used dial-up services to go online. Remember AOL?
Because these services provided slow speeds and pages took a long time to load, the browser developers built something into your web browser called a cache. What this cache does is store local copies of pages you have browsed to, in a folder on your computer so the next time you go to that same page; it can load it quickly for you. That is the good.
The bad is that if that page has changed, your browser will not necessarily load the new version, what you are probably seeing is a cached/old version.
Quite often, we will make changes to a client’s website and when they go to review it, they don’t see the changes, assuming we didn't make them. We then have to remind them to fully clear their browser cache and then refresh the page a couple of times in order to see the new changes.
This is a BIG issue for web developers. Technology experts, like Wireframe Media know to do this, but our clients do not, in fact most people are not even aware their browsed content is being cached especially on mobile devices.
We make it a practice to clear our cache(s) at least once a day, and sometimes up to 25 times, if we are developing a website and need to make sure we are seeing all the actual changes.
Here is a reference guide on how to clear your cache on all of the main browsers and even your mobile devices.
It might be a good idea to make it a regular practice to clear your cache daily or weekly, especially if you have a website and want to be sure you are seeing the updated pages.
