How to Clear Your Browser's Cache

It often occurs that I make changes to an existing website for a client, then send the client a mail informing them of what I have done.

However, it is not an infrequent occurrence that I then receive a mail back from the (sometimes disgruntled) client, saying that they cannot see any changes.

Hmmm… I know I made the changes and I’m viewing them on the live site, so why can’t the client see the same thing?

The answer is because of browser caching.

Browser Caching 101

Each time you access a file through your web browser (if you don’t know what a web browser is, read this), the browser caches (i.e. stores) it in a temporary internet files folder on your hard drive.

The reason that it does this, is so that the next time you open the same page, it doesn’t have to retrieve the file from a remote web server (the computer that hosts the web site), only from the local hard drive.

This results in a big increase in speed for you, the end user.

Browsers cache all kinds of files, ranging from HTML to CSS to images and this is normally a good thing. However, in some situations (such as the one described above), it can lead to problems.

So, How Do I View Changes to a Web Page When My Browser Has It Cached?

Well, the simple answer is to reload the web page in question.

You can normally do this by pressing the F5 button on your keyboard, or by right clicking on the page and selecting reload from the context menu, as is shown in the screen shot (click image to enlarge).

If this doesn’t work for you, try holding down the Control key (bottom left hand corner of your keyboard) and pressing F5. This will force a cache refresh.

For those of you that want a little more technical information on the subject, check out this discussion on StackOverflow which goes into detail about what happens behind the scenes.

Clearing Your Cache Completely

A slightly more draconian (but nonetheless equally as effective) solution is to clear your browser’s cache completely.

Be warned: doing this may also result in your browsing history, download history, saved form data and cookies being erased (depending on the options you select).

You also need to know which browser you are running, as the instructions vary slightly from browser to browser.

And What If My Browser Isn’t Listed Above?

Failing that, ask Google. A typical query could be:

It is also worth noting that you can do all of this and a lot more with the mighty CCleaner.
