Setting Expires headers for static Directory Restlets

[Mike Brzozowski]

Hi,

The Directory Restlet is a really convenient way to serve an entire directory of
static content. But by default it all expires within 10 minutes. Is there a way
to change a Directory so that it returns files with a custom time to live (the
way FileRepresentation does for individual files)? If not, what would be the
best way to subclass Directory to gain this functionality?

Thanks in advance,
Mike
