Add allowCaching attribute to StreamResult
------------------------------------------
Key: WW-2665
URL: https://issues.apache.org/struts/browse/WW-2665
Project: Struts 2
Issue Type: Improvement
Components: Dispatch Filter
Reporter: Al Sutton
Attachments: allowCaching_on_streams.patch
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
