This is a tip for those who might run where giant swarms of gnats sometimes loiter by the side of the road. This tip stems from a run on the Mayan Riviera in Mexico, but I've encountered swarms of gnats in Virginia and Kentucky as well. After your run, always stop and look in a mirror before going into public. Otherwise, you might actually complete a transaction at the resort store and greet five people before realizing you have up to 15 gnats stuck to your face and neck.
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."
