Google announced Chrome 17 today; their top advertised feature was a prerender feature for the omnibox.

When you start typing in the omnibox and the URL autocompletes to a site you’re very likely to visit, Chrome will prerender the page, so it will appear faster--sometimes, even instantly--as soon as you hit Enter.

But, I can't get it to work. I monitor my network traffic (using Charles) and type "" in the omnibox, waiting for some magic to happen; nothing. It autocompletes as soon as I type "go", but it doesn't prerender.

Same for "" ("fa") "" ("st"). The network traffic only starts once I hit Enter.

Is there some way to force it to prerender for certain pages?

Are you sure you are using the latest version? – Synetech Feb 8 '12 at 20:23

Web Developer's Guide to Prerendering in Chrome says,

Beginning in Chrome 17, Chrome itself will initiate prerendering in some cases, based on the user's interactions with the address bar.

So I dont think it'll work always. Use it for sometime. Maybe it'll prerender the pages you visit most.

It performs the analysis based on the history. If he has already been using Chrome for a while, then that is not the problem. – Synetech Feb 8 '12 at 20:24
Yes. I've also seen prerendering while searching at, where you search for a query, wait couple of seconds and the top result usually gets prerendered. – Bibhas Feb 8 '12 at 20:27
@Synetech Yeah, I have been using Chrome for years. – Dan Fabulich Feb 8 '12 at 20:53

You can check which URLs are likely to be prerendered by going to chrome://predictors in Chrome 20 or later. This page shows which URLs Chrome thinks you might navigate to after entering particular text in the Omnibox.

Similarly, you can use chrome://net-internals#prerender to find out when a site is being prerendered.
