Browsers and caching

Which browsers display old cached pages?

[DiAMOndDavE]

A client asked me an interesting question today. They are a real estate agent and typical website visitors return regularly to check for new property listings. They are worried that the returning visitor will see an 'old' version of the listings home page due to the browser caching their last visit.

They want me to put up a message to the effect that the user should hit page refresh every time they come back. Is this necessary these days? Are there any browsers out there that would create this issue?

Most browsers just caché images and not HTML pages. The AOL Browser and to a lesser extent, Opera 6.0 are the main exception to this. However, they won't load a page from caché once the browser has been closed and re-opened.

Mozilla will load from the cache in a new browser session if the page has not yet expired. You'll need to set some HTTP Headers to control when pages expire or get cached, like in jdMorgan's link.
