We've all been there. We're looking at a site and keep refreshing to see if what we're looking for has been updated. But, often times our browsers will cache items on the page (especially images and Flash™ documents.) This enables faster page loads, and less data transfer, which is actually nice. However, if you're a web developer, or someone who checks the tips site a lot for comments, you want to know that the information you're viewing is perfectly accurate. And, you don't want to empty your cache every time you look at a site. So, here's what you do. To get a page to refresh, and not draw from a cache, simply put a good old-fashioned question mark (?) at the end of your URL, and hit "Enter."
But yeah, it's not for the sensitive friends among us. It can come across as hurtful. You just have to be thick-skinned!
