Simple Answer: No.

Lengthly Answer: You don't really want to do this, though at first you might think that you do. Ask yourself the question of what if the user has a 'flakey' network connection? People still use modems & some backwoods phone networks still drop you to lower baud rates, etc... What if the connection simply wasn't properly made? What if they're hitting BACK for a reason? NO,nonononono. You don't want to even TRY this.

Further, you'd be messing with the average surfer's normal procedure of 'doing their thing.' That's a great way to become unpopular fast. Don't try to outguess your users & treat them like they're stupid. (even if they are)

They real way to do this is to have the server see what they're doing, anticipate it, & deal with it gracefully.

Exception to the rule:So you're dead set on doing this huh?... Simple. Open a new browser window. There will be nothing to go BACK to...
