Hmmm, right... Sorry..
It does work on generate/serialize, but perhaps I was wrong and doesn't
it work on matches that only contain a reader. Funny though..
Have you tried the following already?
<map:match pattern="download/**">
<map:read src="{1}" mime-type="application/x-download"
/>
</map:match>
(or something alike?)
Kind regards,
Geert
