Prevent Browsers from Caching

Many browsers know that people don't always have 3 megabit connections to the internet (why are you staring at me), so they save websites onto their viewer's computer. Then, when the viewer visits the website again, the browser puts the outdated version of the web page it has saved in front of the viewer. This process is called caching. If your page is constantly updated, it is usually a bad idea to have browsers cache your website. Therefore you will need this html tip:
Put this code right after the <head>:
<META HTTP-EQUIV="Expires" CONTENT="Tue, 01 Jan 1980 1:00:00 GMT">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

Do not worry about the queer date, but worry about putting the code onto the least lines as possible. Your page will now probably never be cached again!
This web page also never gets cached.
