setting headers on non-jsp files

[Daniel Blumenthal]

Happy holidays, all!
 
Is there any way to set HTTP headers on non-jsp files, using only tomcat?
What I would like to do is set javascript files to "no-cache", so that the
browsers pick up the (fairly frequent) changes.
 
Any ideas?
 
(I could just turn them into jsp files, and I may yet do so, but there are a
lot of them...)
