Rails - Feb 2006 - Making the browser cache an action

Hi!

What HTTP headers do I have to sent to make the browser cache the
output of an action?

I tried:

request.delete(''Cache-control'') but no luck.

It''s an action that sends an image to the browser, hence I need that.


Thanks,
Rob

Wow. This is what I was looking for:

# Set cache to expire in one year
expires_in 1.year



Beautiful..

Where do you use expires_in? Can you set it within a controller?
