You just had some changes made to your website. Developer says he/she is done so you view your site but none of the changes are there. (!) You call your developer/designer and say “where are the changes?”.
In most cases this can be resolved when you clear your browser cache!.
The browser cache is a storage area in your browser that holds all the files of web pages you’ve visited. This conserves bandwidth because the next time you visit that page the trip to the web server is not necessary, files are already right there in your browser cache and the page loads that much quicker.
When you change an image by replacing the old with a new that has the same filename as the old one, the old one can get stuck in the browser cache.
Stylesheets will stick in a browser cache too.
If you are having work done on your website, it is a good idea to learn how to clear your browser cache. There are ways to prevent stylesheets from sticking in the cache but these techniques can be tedious and many developers do not use them.
