Opera forced check for new page versions

[Cienwen]

Hello,

I have a client who uses Opera. Every time I update her homepage her browser still shows the old cached version. This does not happen with my IE or FireFox. Does anyone know some code that will tell Opera to check for updated versions? I’m looking to set things up to force the browser to check because I can’t teach everyone who looks at this site how to set their browser preferences.

Any help would be appreciated.

Opera is renowned for caching documents more frequently and for longer than other browsers. Opera for example never checks the cache headers when clicking back or forward.

Are you creating static pages or generated ones? Are you including and cache-control headers or meta tags?

My pages are static, but the home page (index) is changed every 4 weeks. I do not have cache control meta tags. How would they look?

If you are using static pages then the server will automatically configure the caching for the page in relation to the last modified date on the file - so if you leave the page unchanged for four weeks, many servers will instruct caches and browsers to keep a copy of the page for an amount of time which will vary between several hours and several days.

How to set up caching depends on your server software. Are you running Apache, IIS or something different?

Have you tried using F5? In my experience, Opera performs a full refresh and picks up all changes.
