Let's say I create an index.html file with just
<P>Hello World</P>
If I visit that website, it says "Hello World" on screen.
If I modify that website to
<P>Goodbye World</P>
and visit that website from the same machine it will still say "Hello World" unless I refresh.
I've seen this with quite a few websites and was wondering how to do I refresh at the start?
I know how to do an automatic refresh every x seconds, but I'd prefer to do it just once.
It's probalby because the page is loading from the cache - i.e. the browser is not making a fresh call to the server to get the HTML file rather it's just loading it from the temporary internet files folder on your hard disk.
META tags in a HTML file can (to some extent at least) protect against caching - they basically can pass a "no-cache" message to the browser .. Google should give you lots about this ... there are other methods too (more complex) - I'm no expert perhaps others can volunteer.
