I don't know whether I need a bit of html or javascript to do this, so apologies if in the wrong place

I need to put something in a webpage which automatically reloads the newest version of the page in the browser. (At least, that's what I think I need...)

THe problem is that I have a page with various products for sale with paypal buttons, which I update from time to time. I have had several people click on buttons which don't exist anymore, and paypal still takes their money despite me deleting the buttons in my paypal account, but they get no product. I want to do something which ensures that when this page is loaded, the visitor must get to see the new version, even if the old one is in their cache.

I tried to do this with meta <meta http-equiv="refresh" content="0; url=page.html"/>

but it just refreshes constantly. I know I can change the time limit, but is there a way to refresh the page immediately, but only once?

add

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="expires" content="0">

to the pages, User agents should then reload the page from the server rather from their local cache.

Perfect thanks Chris! Now, what does that code actually mean?

<meta http-equiv="pragma" content="no-cache">

No cache just tells the browser not to use cached pages and therefore it must call the web server for the page again

<meta http-equiv="expires" content="0">

Expires sets the date that the page expires (value of 0 means to expire immediately)
