no-cache; does not work

In my head:

[code=php]<meta http-equiv=”pragma” content=”no-cache”/>
<meta http-equiv=”expires” content=”-1″/>
<meta http-equiv=”cache-control” content=”no-cache”/>[/code]

Which used to work, but now it doesn’t seem to work.
I’ve recently upgraded most of my pages with:

[code=php] <!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”
“http://www.w3.org/TR/html4/loose.dtd”>[/code]

and validated at w3c with no errors.
I was hoping that this upgrade would fix the problem but
it has not.

I really need it to work because when I make changes they
won’t show up until I refresh the page.
