Image is not being refreshed

[hstang]

Can anyone explain why an image cannot be refreshed?

I have the following:

<s:div id="toBeRefreshed">
 <h:graphicImage value="/faces/download/image/someImage"/>
</s:div>

Usage:

<a:poll interval="2000" reRender="toBeRefreshed"/>

Every 2 seconds, the image is not being refreshed when the underlying image did in fact changed. I know it's changed because if I start another browser client and go to the page that consist this snippet, it'll show the updated image.

Hi,

That happens because browser caches images.

There is some solution for this???

try to append a pseudo request parameter so the url is permanently changing

e.g.

value= "...someImage.jpg?id=123"

f:param at media output solves just the same problem. and as it pointed to timestamp - resource url is always different so it's not cached.
