I have a dynamic website system that my clients use to change their webpage
conten online. Sometimes the new change isn't visible right away to a
browser. I have the following in every webpage's <HEAD> section:
<META HTTP-EQUIV="EXPIRES" CONTENT="0">
which on previous investigation was supposed to be a solution for this. All
I want is a definitive solution so that when a browser makes a call to my
server for one of my pages, everything along the line that has a cached copy
of the page is going to say "Aha! The browser wants the latest version of
this page! I'm going to pass this request up the line to see if their is a
more recent version instead of sending it my cached copy". (Yup, that is how
browsers and ISPs speak to each other). What do I have to do to my webpages
to ensure this happens? At the same time, I don't want it to be getting the
page all the way from the server if the page content hasn't changed. In
other words, I just want the cacheing to work properly!
Sorry if this isn't an explicit ASP question but no one in the HTML groups
I've tried has any idea what I'm talking about and I'm hoping that those who
frequent this room will have a better handle on the whole
client/server/caching problem and the solution!
Thanks!
