LastModified

Supports last-modified HTTP requests to facilitate content caching. Same contract as for the Servlet API's getLastModified method.

Delegated to by a org.springframework.web.servlet.HandlerAdapter#getLastModified implementation. By default, any Controller or HttpRequestHandler within Spring's default framework can implement this interface to enable last-modified checking.

Note: Alternative handler implementation approaches have different last-modified handling styles. For example, Spring 2.5's annotated controller approach (using @RequestMapping) provides last-modified support through the org.springframework.web.context.request.WebRequest#checkNotModified method, allowing for last-modified checking within the main handler method.
