Clear Browser Cache.
compliments of Alison G and Alfred P
I added the following code to the master page header of my site:
<META HTTP-EQUIV="PRAGMA"
CONTENT="NO-CACHE">
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
You probably
only need one or the other (not sure), but they should ensure that visitors see the
latest version of your page(s) each time they return. It'll mean that content will
have to reload, I know, but it should avoid what you've been experiencing. I added
it when visitors to my site started telling me that such and such was still the old
version. Since I added this code, I haven't had any complaints, so I assume it's
working. Others will, I am sure, come along with caveats!

Serif Forum - Clear Browser Cache
According to this page the Expires meta tag doesn't actually prevent caching (so
a cached copy can be used, for example, if you press the 'Back' button) but it does
ensure that the remote Web server is contacted on future requests by the user. The
following should cover all bases (IMO, YMMV, etc):
<META HTTP-EQUIV="Cache-Control"
CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires"
CONTENT="-1">
