hi,
a while ago i did a portfolio site for a photographer which loads lots of 
images using an xml file. everything works fine. when you return to the site it 
loads more quickly as do the images, i guess because the browser has cached 
them. but sometimes after the site has been updated (ie. photos have been added 
to the portfolio and put in the xml file) it doesn't recognise that new content 
is there and loads the same old photos. only after clearing cache or private 
data and then returning to the site does it load the new images. obviously this 
is far from ideal.
i'm not sure if its because the swf gets cached or the xml gets cached or both.
i've just seen a note on the adobe site about using "Expires" header in an html 
page or PRAGMA header to prevent the contents being cached but it would be 
great to not cache the swf and xml which are very small files but cache the 
images so the site runs quicker.
thanks in advance for any help,
david
