update and cache problem

[essahyd]

hi guyz

i have a website that is to be update every week

what i update in the weist eis the images and a few html pages

no the problem i have is when i update the pages i cant see the updated version sometimes

i use Internet Explorer 6 so i hold ctrl key and press refresh so the cache clears (delete the temporary files) then only things work fine

But my question is what will my user see will he see the updated version or the old version as all users don't know to clear the cache. and more over they even not know the site has been updated

so please tell me a way that will always show updated version to my nowise user who have very limited knowledge of the web

thanks u
