title: HMTL5 manifest cache and pre load
body: <p>could someone spread some information on html 5 manifest app cache for me? My question is, if you include an image or file on the manifest, should it load the file immediately and then not have to reload the file any more?</p>
  
  <p>For example, I have a web application where i would like to preload all the images at the beginning, can i include them in the manifest or do i still need to use JS for this.</p>
