title: What keeps the back button from working on some sites?
body: <p>So we've all been to some annoying websites that disable the back button in your browser.  This can be circumvented by quickly pressing the back button two or three times.  My question is: what is exactly happening when the back button is disabled and 2.) why does clicking the button two or three times fix the problem?  Dying for an answer, don't let me down, SO! :)</p>
