If we reload the video we have watched at least one time, it was required to download the whole video again. YouTube has introduced the new cache feature. For instance, you click here to watch the YouTube video. Press pause first and wait the whole video to be downloaded as cache. Next time when you visit the page again or press the reload button, you don’t have to wait. The red bar will be full within 1 second.
I have tested in Firefox and Safari 4. It seems that it only works for Firefox, but users reported it works in Chrome and Safari 4. Note it may not work properly if you have pressed HQ or HD button. The cache function is useful for those videos you watch frequently.
