Once it's cached in the browser there's not much you can do about
it, the browser will store the cache settings at the time when it
cached the page and if those settings say "don't check again for a
month" then, generally, it won't.

If you want the page to never be cached then you need to set the
expiry header.  With Apache servers this is quite straightforward
and can usually be done in the directory's .htaccess file:

ExpiresByType text/html "access plus 0 seconds"

This is example was take from HTML5 BoilerPlate:

Append some junk querystring to the end of the URL, like
example.com/index.html?20120803132400. Every time it changes, stuff will be
refreshed. Wouldn't really recommend doing it for regular pages because it
makes the URLs look messy, but if you're trying to refresh scripts or
images, go nuts.

Re: [WSG] how to force a cache bypass?

2012-07-20 Thread Danny Vose 
Are! you again Bob,  we will have people complaining about off topic again lol

You can do this Bob

Place the following meta tag within the head of your HTML document. When used 
to refresh the current page, the syntax looks like this: It "should" work in 
all browsers but dont hold me to that and do a check mate. This tells the 
server to call up a new version of the page each time its requested. (or 
refreshed automatically in 600 seconds if they stay on the page)

  OK, this isn't about standards, but it's more interesting than knowing that 
folk are not in the office . . .

  How can I make a web page appear as the latest version in all browsers, i.e., 
perform a cache bypass?  And I don't mean for me - I mean for all visitors to 
the page?  Is it possible?
