Interface CachingHeaders

public interface CachingHeaders

Represents the different types of caching headers used by Confluence. Applies the "Cache-Control" and "Expires" headers to a response as specified in the HTTP 1.1 specification (RFC 2616).

This implementation intentionally does not specify the Pragma header, which is sometimes mistakenly used by servers to try to control client caching. Pragma is actually a request header, so shouldn't be generated by this code.

Since:

3.0
