How to: Clear Web Browser Cache

As you visit web sites, browsers save copies of the visited websites on your computer in a temporary location in your computer called cache. This helps your computer load web pages more quickly on subsequent visits.

 While this is a great time-saving feature, it can occasionally cause conflicts on some pages if the cached copy is out of date or corrupted.

You may find the site’s webpage taking a long time to show up. You may experience some websites not showing up at all. This may be the cause of your Internet speed or your browser cache.

What is a cache in computer sense?

A cache is a repository for stored data that is used to expedite the process of retrieving data. Common cache are webpage caches, hardware caches, software caches and memory caches. Caches are used to speed up a process so that data does not have to be recomputed or fetched from its original location. This feature will improve performance significantly. A cache hit is when a program checks the cache for previously stored information and finds it to be used again. A cache miss is when the data is not found within the cache thus will look to a larger, slower memory source.

Internet browsers use caching to store HTML web pages by storing copies of visited pages and then using the copies to render when you re-visit the web pages. If the date on the page is the same date as the previously stored copy, then the computer uses the one on your hard drive rather than re-downloading it from the internet.

Do we need to empty the browser cache?

Many times web developers make updates to files that comprise the site to push the changes or add new features. If files are changed that your browser has cached, it may keep serving the old cached version of the file which you may not see the most recent changes. This situation would show browser errors like Run Time error, buttons missing on the page, or get messages stating the webpage cannot found. Clearing the Cache and Cookies in a browser generally fixes these issues.

Some browsers have settings to:

    Check for new versions of stored pages every time you visit the webpage.
    Check for new versions of stored pages every time you start your browser.
    Automatically check for new versions of stored pages (commonly set).
    Never check for newer versions of stored pages (general never select this one).
    Delete browsing history when you exit your browser.
    Manage cache storage size on your computer. Some are automatic setting and some are fixed such as 250MB to 250MB.

No matter what settings you may find and set, you still may occasionally need to empty the cache.
