Page load times can be significantly improved by asking visitors to save and reuse the files included in your website
What this module does for you
Browser caching works by marking certain pages, or parts of pages, as being needed to be updated at different intervals. Your logo on your website, for instance, is unlikely to change from day to day. By caching this logo image, we can tell the user's browser to only download this image once a week. Every visit that user makes within a week would not require another download of the logo image.
By the web server telling the browser to store these files and not download them when you come back saves your users time and your web server bandwidth.
The main reason why browser caching is important is because it reduces the load on your web server, which ultimately reduces the load time for your users.
Reduces page load times for repeat visitors
Particularly effective on websites where users regularly re-visit the same areas of the website
