no-cache header in htaccess file causes more harm than good

The sample boosted htaccess file has this in it:

  <IfModule mod_headers.c>
    Header add Expires "Sun, 19 Nov 1978 05:00:00 GMT"
    Header add Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
  </IfModule>

I believe this causes more harm than good because it also applies to all images. Thus, on every page load every single page element image is reloaded.

Either don't enable mod_headers in your apache, or just delete these lines. The actual pages still get both of these headers (I'm assuming some other drupal module is adding them) and the images don't get them, so at least for me, the default drupal behavior is correct. I'd die if every page load required reloading all the images.
