Hi Mike, I am finding that Safari is not honoring the meta tag to turn off caching. I thought I would give your method a try. I’m not sure I am doing it right though because that isn’t working either.
(Firefox does everything properly.) I was thinking from your description that it would look something like: http://www.yourwebsite.com/coolpage.lc#48432 <http://www.yourwebsite.com/coolpage.lc#48432> Is the above example of what you are discussing correct? If not could you please post an example?
