Expires & Cache control

[SmartTux]

Hi,

This is a very basic newbie question. I would like to know what "expires" and "cache control" options actually do. The readme doesnt give much info other than Charles suggested it.

Thank you.

To s3, nothing direct.  They just set values that will be returned when something does a GET for that item.  Exp and CC are used by browsers and proxies to determine how (long) to cache a resource.
