Last accessed v. checked

I'm looking over a log of temporary internet files for an XP machine. I'm not sure the IE version. (The machine is no longer available.)

In the list of files are some images that I am looking at closely. They all have a Last Checked timestamp that is seven hours before the Last Accessed timestamp. (Normally the two time stamps between the two dates are identical.)

What would cause this? One idea is that the person using the machine could have disabled caching on that day. However, this isn't likely. Is there any other explanation?

thanks.

thanks for the reply. i actually saw the page that you referred to prior to posting here.

why would a browser access a page without checking to see that the page was in cache? I'm trying to explain the large gap between last accessed and last checked for the temporary internet files i'm researching.

thanks.
