org.fenixedu.academic.ui.struts.action.teacher.siteArchive.streams.FetcherServletResponseWrapper
This response wrapper is used by the fetcher to prevent any content generated by the resource to be written to the wrapped servlet response thus commiting the response and making it useless.
The {@link #getOutputStream() ServletOutputStream} and {@link #getWriter() PrinterWriter} returned by the response will write to the provided stream ratter than to the wrapped response. If the responseis of type "text/html" then an intermediary {@link org.fenixedu.academic.ui.struts.action.teacher.siteArchive.streams.TransformUrlsStream} is used to ensure that thecontent is transfomed using the target resource's rules. @author cfgi
