When you experience problems with a webpage, you may often hear that the first thing you should try is to clear your Internet browser's cache. Each browser (e.g. Google Chrome, Firefox, Safari etc) is different, as so, clearing it's cache is specific to each one.

Browser cache (or HTTP cache) is the information from websites that you visit which your web browser stores in your computer's memory. This information is made up of the HTML structure (the code-archetecture of the webpage) and it's associated images and also other files that dictate how the page looks and functions. The benefit of these files being cached in your computer's memory is that each subsequent visit to that same webpage displays the page, and functions, much faster.
You may notice the effect of this when you first visit a page; text may load quickly but there may be a lag in the images loading. However, the next time you visit the same page, everything loads very quickly. This is because your computer is acessing many of the files necessary to display the page from your computer's memory, rather than sending a request for the files to the website and waiting for the information to be returned and then displayed on your screen. This caching of files saves you time and also reduces bandwidth on the website's server.
If a website updates the content of a webpage (for instance changing images or other files that govern the page layout or functioning on the page itself), but your computer is loading those items from the cached files on your computer, then what is displayed on your screen may differ from the updated information on the actual website.
How this applies to The Rehab Lab: On occasion, The Rehab Lab may upload slight changes to certain files that govern how certain elements of the software functions. If your computer is accessing an 'older version' of the software, because your browser is constructing The Rehab Lab with files cached in your computer's memory, then one of three scenarios can occur:
1. You notice no issues or change whatsoever
2. You notice a slight lag in the way the software is functioning
3. Your notice problems that result in the software not displaing or functioning correctly.
In order to fix these issues it is important that your browser is accessing the latest version of The Rehab Lab. To do these, the older files that are stored in your browser's Internet cache need to be cleared in order to force your computer to load the website correctly.
