Another cashing question .....
..... regarding cashing of images.
I use a SVG image in shape of a piechart which is serialized into a jpeg and
displayed in a serialized html page.
Upon submitting the HTML page with choosen parameters, the same HTML page
will be shown again but with different text and a new shape of the SVG
piechart. However this is not the case while the image seems to be cashed,
and only upon clicking the refresh button in the browser the new image will
be displayed. Do anyone know how to turn this cashing of images off in
cocoon 2.
Thanx for your help!!
Regards, Markus

Cocoon 2 can not turn of caching of images in your browser (and, it is
clear from your email, that caching occurs in the browser).
However, you can set some headers using action (try HttpHeaderAction)
which will help you disable browser's cache (and proxy's cache). These
are:
Expires: 0
Pragma: no-cache

PS Is it FAQ?
PPS This answer applies to 2.0.3 and 2.1, but 2.1 will have ability to
set expires header on pipeline level.
