You would like to disable caching your pages in dispatcher but you dont want to use dispatcher caching and would like to handle this dynamically in your pages.
With the Dispatcher release 4.0.0 (and higher) a new header named "Dispatcher: no-cache" is introduced. This header informs the dispatcher not to cache the response. This header will then be removed by the dispatcher before forwarding the response to the client.
In order to disable caching in the dispatcher, add the header "Dispatcher: no-cache", i.e. in your JSP:
<% response.setHeader("Dispatcher", "no-cache"); %>
