...Chrome will now start loading some web pages in the background, even before you’ve finished typing the URL in the omnibox. If the URL auto-completes to a site you’re very likely to visit, Chrome will begin to prerender the page.
I am still watching my logs to see how this prefetch is implemented. (Yes, I should have downloaded and tested it myself but I've been otherwise occupied.) I'm hoping that it follows prior art and can be blocked/filtered as desired. See Chrome Joins Mozilla , Cre8, 08-August-2011.
Pre-fetch is an horrifically bad idea from a webdev's perspective as it distorts page view numbers, bounce rate numbers, ad delivery statistics (nasty thought: perhaps that why G likes the idea...)... Plus it goes through bandwidth like a bot. This is even worse in some ways than the referer query removal pita. Managing Google is becoming bloody time consuming. Cost:benefit ratio is definitely increasing...
Off to find something inanimate to kick.
