> The attached patch adds the attribute "allowCaching" to results that use
> StreamResult. The allowCaching attributes lets developers configure whether
> or not the stream result should be cached.
> If set to true (which is the default) the result can be cached by any
> downstream proxy or the client, if set to false the following headers are
> added to the response in order to discourage caching by proxies and clients;
> Pragma: no-cache
> Cache-Control: no-cache
