This might be a FAQ but I've searched and just found a bunch of different results. Some old and some even older. What do you use to stop caching? IE users of my current project have reported problems of pages on updating. I'm not setting any caching at all so that's what IE does out of the box. (Firefox is not having a problem). Currently I'm using this: now = DateTime().toZone('GMT').rfc822() response.setHeader('Expires', now) response.setHeader('Last-Modified', now) response.setHeader('Cache-Control','no-cache') By inspection with LiveHTTPHeaders in Firefox it sets them all but I'm not 100% certain they will work. There's also the concern that I think M$ IE might have a bug in relation to that 'Cache-Control' header. There's some strange and now I just can't remember it or find out about it on google. So, what do you people use? Willing to share some of that? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
