Safari: Reloading a page always bypasses cache

Article: TA24891 : "Safari: Reloading a page always bypasses cache" has been abanodoned by Apple since February 2012.

"When you reload a Web page in Safari (by clicking the Reload icon or by pressing Command-R in Mac OS X or Ctrl-R in Safari Beta 3.x for Windows), cache files are bypassed. You don't need to hold Shift or any other modifier keys."

=======

One assumes that this is the result of the changes to clearing cache in Safari for Mountain Lion -- Version 6.0.2 (8536.26.17) -- you must have the Developer drop down "installed" to "Empty Caches."

Formerly, the instruction was:

"Hold Shift while clicking Reload, or press either Ctrl-F5 or ⌘-R on a Mac"

So the question is:

1- What is the technique for reloading a page WITHOUT retrieving information from the cache?

2- And... does the earlier instruction still apply to versions of Safari prior to Safari 6?
