So do you mean that I can wrap my pipeline into
<map:read src="foo.jpg">
< ... my pipeline ... >
<expires>1000000</expires>
</map:read>
??
My url is someting like ... cocoon/graphics/gengraph?value=10&point=5 for
generating svg and then serialised as jpegs.
Or do you mean I can stick an <expires> into my pipeline? Does that mean the
pipeline will check if the input url is the same, ... if it is not the same
then... it will run and it is the same and it hasn't expired, it will
generate it again?
Is there any documenation of <expires>?
