As a golf course, our prices change regularly, depending on the time of year. I try to keep prices all on one page to avoid people having to bookmark different pages (ie: Winter Prices, Spring Prices, etc).
However, last year after we went to Spring pricing, I had customers come in mad because they’d pulled the page up and saw Winter pricing. I knew what was going on . . . CACHED PAGES!
Is there a piece of code that will force a fresh load on a page?

Can you share what environment your working in? Is your site static html, built using wordpress or some other software? And can you share a link to the site?
Cheers!

You could use a bit of code in your page header like:
<META HTTP-EQUIV=”CACHE-CONTROL” CONTENT=”NO-CACHE”>
or
<META HTTP-EQUIV=”REFRESH”
CONTENT=”15;URL=http://www.yoursite.com/thepricingpage.html”>
Google these for more information, but they both should work.

@dedimason SME user @michaelraia shows you 2 ways to update your pricing content to make sure its not cached.
Also, I strongly suggest that you put a header and disclaimer on your pricing content.
A header saying “Winter 2011-2012 Pricing” then you can update it later to say “Spring 2012 Pricing”
Then a disclaimer like prices subject to change by season.
If you have a dynamic website, you’ll need to see if your server is caching the content as well. Do you know if this is true?

@juleswebb ~ The sites are static HTML.
@michaelraia ~ Thank you!
@robmitchell ~ The header has always changed with the price changes but when I read what you wrote, I realized that I could add a line that says “Good Through [DATE], refresh page if you’re seeing this after [DATE].
I have a dynamic DNS if that’s what you’re asking. I’ll have to check to see if the server caches pages. I do know that I keep my own cache cleaned daily and when I update the pages, I have no trouble with old pages showing on my computer.
Thanks so much everyone!

You can’t always rely on meta tags in an HTML page for controlling caching. (sorry to disagree with you @michaelraia –if you have supporting documentation I would be happy to learn and recant if I’m incorrect.)
Assuming that your site is hosted on a server that’s running the Apache Web Server software (contact your hosting provider to find out) I would add the following to your .htaccess file

Sorry, The code didn’t present well when I saved the comment so I’m linking to a text file instead: Expires Headers

It’s a little above and beyond what you need, but it will do the job. This is the same code I use in my site.
Here are some reference links.http://www.askapache.com/optimize/speed-site-caching-cache-control.htmlhttp://www.htaccess-guide.com/

@juleswebb ~ thanks for that info! Yes, I’m pretty sure the host is using the Apache Web Server software. I’ll double check, since I just switched hosts.
