ResourceResponse defines an object to assist a portlet
for rendering a resource.
The difference between the RenderResponse is that for the
ResourceResponse the output of this response is delivered
directly to the client without any additional markup added by the portal.
It is therefore allowed for the portlet to return binary content in this
response.
A portlet can set HTTP headers for the response via the setProperty or
addProperty call in the ResourceResponse.
To be successfully transmitted back to the client, headers must be set
before the response is committed. Headers set after the response is
committed will be ignored by the portlet container.
The portlet container creates a ResourceResponse object and
passes it as argument to the portlet's serveResource method.

Creates an action URL targeting the portlet.
Action URLs are used to create forms or links that, when triggered,
update the render state in a non-idempotent manner.
If a request is triggered by the URL, it results in an action request. The returned action URL will not contain any private render parameters per default not contain any parameters from the current request. The returned URL can be further extended by adding portlet-specific action parameters, portlet mode, and window state. If no additional portlet mode, window state or security modifier is set on the URL, the values from the current render or resource request are preserved. Public render parameters do not need to be explicitly added to the returned action URL, unless the public render parameter value is to be changed. Any public render parameters associated with the portlet will automatically be available during action request processing resulting from activation of the URL. If a public render parameter value is set or removed on an action URL, then the public render parameter will be set to the new value or removed when the URL is activated.

Resource URLs are used to trigger requests for content that applies
to the current portlet view state.
If a request is triggered by the The security settings can be changed for the URL. If the security settings are not explicitly set, the values governing the current request are preserved. The current render parameters, portlet mode, and window state are preserved depending on the cacheability setting for the returned resource URL.
If cacheability is set to If allowed by the cacheability setting, public and private render parameters are added to the URL with their current values. The render parameter values cannot be changed on the URL. The URL can be further extended by adding portlet-specific resource parameters.
The URL will contain the current
