Your browser might be lying to you: How to clear the cache

Did you know that you might not be seeing the most recent version of a webpage? Here’s why, and what to do about it.

The why

Internet Explorer and other browsers keep copies of the pages you’ve visited and their graphics, and save them to your computer using a memory called the cache. The purpose of the cache (pronounced cash) is to speed up your browsing experience. The problem with that system is you might be viewing pages that are outdated, without even knowing it.

I run into this with clients and colleagues from time to time. If I update their website and they say, “But I still see the old information (or old graphic),”  it’s a telltale sign that they need to clear their browser’s cache.

The easy fix

If you’re using Internet Explorer (version 8), on the top menu go to: Tools, then Internet Options. Under browsing history, “delete.” And also be sure the box is checked for “delete browsing history on exit.” Click OK to save. Then exit, and restart Internet Explorer.

If using Firefox, on top menu go to: Tools, Options, then Privacy. Under history, choose: Firefox will “never remember history.” Then click the link to “clear all current history.” Click OK to save. Then exit and restart Firefox.

That should clear your cache, and you should then see current web graphics/pages instead of old ones.

 

 

How to create a QR code

You’ve seen these curious-looking barcodes, called QR codes (“quick response”), popping up lately, especially on advertisements. Have you ever wondered how to create one of your own? Wonder no more.

I created this one online using a free code generator, and it couldn’t be any easier. Two to try are ZXing or Delivr. You simply select what type of code you want to create, fill in the blanks, and voilà! — a code graphic is instantly created for you. You then save the graphic for your own use.

While I’m not wanting to plaster these things everywhere, I have integrated QR codes into a few recent projects:

  • On a business card: A code embedded with my contact information, that when scanned adds me to their phone’s address book.
  • On a nonprofit’s donation solicitation: A code labeled “Scan here to give online” takes the user directly to the organization’s “Make a Gift” webpage.
  • On the back cover of a magazine: A code placed beside a screen shot of the magazine’s website takes readers to the site.

Cool as it is though, this technology is still new. Many people do not yet know what these codes mean or how to scan them. Be prepared to explain that they’ll first need to install a free QR code reader app on their phone.

If you’re using a QR code on marketing materials, I suggest including a brief text explanation under your code graphic, such as “Scan with a smartphone to see a video of our product in action!”

And be sure to think through the user experience and the location of the code.
