Allows server caching of current image

Synopsis

• image_expire seconds

Description

NOTE: Image generation is experimental in the current release of NeoWebScript™.

Turns on server-side caching for the current image being generated, and sets an expiration time on the cache to seconds. (0 is a valid value for seconds, and will cause it to always be expired.) Cached files are served out obeying the \"If-modified-since\" header, allowing for client-side caching as well.
