Can't believe I'm posting this question, but here goes. (After you read the specifics, the "I'm asking because someone asked me" might seem lame, but the truth is that someone asked me and I wasn't sure)

Suppose a person goes on his home computer, signs onto Google/gmail, and accesses a site that he normally shouldn't access at work ( e.g. www.AdultSite.com)

OK, then a day later, that person is on his work computer at his work location, and connected to his work network. He also launches gmail (which the company permits) and signs on.
Then that person opens a new tab in chrome. The feature of chrome that shows recent web pages as quadrants on the main browser page kicks in....and on the work browser, he sees a clipped version of www.adultsite.com

There is no proof that the person actually explicitly accessed www.adultsite.com from his work computer. It clearly came from a login profile associated with his gmail account.

Here is my question:

When that person connected at work....and it showed a clipped image of www.adultsite.com in the work browser, do you think Google was simply pulling a static image of that site from a Google cache in the cloud....or did Google actually (unbeknownst to the person) access www.adultsite.com, and show a stripped down version of the page "in real time"?

Thanks in advance for any info...
Kevin
