IE always refreshes images

[Paul Westrich]

Hi,

I have a strange problem with IE presenting my website.
Every time I reload a page or load a page containing images
already stored in the cache folder the images are also
refreshed instead of just staying quietly in their place.
Thereby the pages get a "nervous" appearance. Other browsers
(Firefox, Opera, Netscape) don't behave like this when
reloading the very same pages. The Code (html, CSS) is clean
and totally valid. It can't be a problem of my PC since it
also happens on other computers.

Any ideas about the cause for this and how can it be avoided?

Your help will be greatly appreciated.

If your Web server keeps updating the date/time on these files then IE will
be forded to download the files every time.

Sorry but this cannot be. Because the described phenomenon
also exists offline and when the required images are already
in the cache. What I mean is not the new download from the
server or getting images from cache but the "refreshing" of
the images on the screen instead of IE just leaving the
images where they are as Opera and Firefox do it.

What you are seeing is by design. If you request a refresh, IE will
redownload content; Ctrl F5 will force a complete refresh, overriding the
settings applied at Tools, Internet Options, cache settings that can
sometimes be damaged by using the 'automatically' setting.

It can depend on the server you are connecting to.
E.g. Apache is known to send a Vary: header with images
which IE often treats as a signal of non-cacheability.

See the reference links from a previous post for more detail
