This might be a FAQ but I'm willing to take a chance. In class ImageFile (from App/ImageFile.py) the following headers are set when you view an ImageFile object: <pseudocode> 'Content-Type': self.content_type 'Last-Modified': self.lmh # RFC1123 'Cache-Control': 'public,max-age=3600' </pseudocode> What is the difference between 'Cache-Control' and 'Expires'? What is best to use and for what? I no longer know exactly why but in all my stylesheet DTML methods I set 'Expires': (DateTime()+10/24.0).rfc822() # 10 hours but not the 'Cache-Control'. Should I use both? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
