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?
