ClientCache plugin

Installed by default. Sets cache-control, expires (if configured), and last-modified HTTP headers.

Configuration

  1. Add <clientcache minutes="1440" /> to the <resizer /> section. This controls how many minutes in the future the Expires header will be set to.

Default behavior

Cache-control: public is sent for all anonymous requests. Cache-control: private is sent for all authenticated requests. 'Last-modified:is sent based on the modified date of the source file.Expires` is sent only if 'minutes' is configured in web.config. For 24 hour expiration, use 1440 (suggested value).
