Hi,
Safari, at least as of version 3.1.1 (5525.20) does not seem to
respect the headers that control local page caching. The Safari FAQ
claims to show how to do this:
http://developer.apple.com/internet/safari/faq.html#anchor5
Returning
last-modified = ("Wed, 04-Jun-2008 00:10:53 GMT");
cache-control = ("no-store, no-cache, must-revalidate, max-age=0, post-
check=0, pre-check=0");
expires = ("Mon, 26 Jul 1997 05:00:00 GMT");
date = ("Wed, 04-Jun-2008 00:10:53 GMT");
pragma = ("no-cache");
still results in Safari using the local cache instead of making a trip
back to the server. The Web Inspector in Safari show that it is
getting these headers, but it seems to ignore them. I have reported
this to Apple.
Obviously, this has rather serious implications for those of use
deploying dynamic web applications. The back button is hard enough to
deal with when the browser works correctly!
Any suggestions for work arounds gratefully attempted.
Chuck
