Description copied from class: Resource

Allows implementations to do configure the response, like setting headers etc.

Overrides:

Parameters:

See Also:

Resource.configureResponse(wicket.Response)

setHeaders

protected void setHeaders(WebResponse response)

Subclasses can override this to set there headers when the resource is being served. By default 2 headers will be set if the Resource is cacheable

 response.setDateHeader("Expires", System.currentTimeMillis() + (3600 * 1000));
 response.setHeader("Cache-Control", "max-age=" + 3600);
 

So if a resource wants to control this or doesn't want to set this info it should override this method and don't call super.

Parameters:

response - The WebResponse where set(Date)Header can be called on.
