cross browser - What to do with chrome sending extra requests?

Google chrome sends multiple requests to fetch a page, and that's -apparently- not a bug, but a feature. And we as developers just have to deal with it.

As far as I could dig out in five minutes, chrome does that just to make the surfing faster, so if one connection gets lost, the second will take over.

I guess if the website is well developed, then it's functionality won't break by this, because multiple requests are just not new.

But I'm just not sure if I have accounted for all the situations this feature can produce.

Would there be any special situations? Any best practices to deal with them?

Update 1: Now I see why my bank's page throws an error when I open the page with chrome! It says: "Only one window of the browser should be open." That's their solution to security threats?!!

Your best bet is to follow standard web development best practises: don't change application state as a result of a GET call.

If you're worried I recommend updating your data layer unit tests for GET calls to be duplicated & ensure they return the same data.

(I'm not seeing this behaviour with Chrome 8.0.552.224, by the way, is very new?)
