They are retrieved simultaneously, but only as they are requested by
the end-users' browser.

  Squid doesn't attempt to parse HTML pages and pre-fetch objects to
anticipate the browser as Cacheflow claims to. The Cacheflow users I
talked to seemed pretty dubious about whether that is really any
improvement. To take one obvious point, if the user has ad-blocking
software, or has image loads turned off, or simply clicks on to the
next page before all the images on the first load, then Cacheflow has
just wasted a lot of bandwidth, time, CPU, and disk downloading objects
which will never be seen by anyone.
