java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

org.broadleafcommerce.common.web.util.FileSystemResponseWrapper

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class FileSystemResponseWrapper
extends javax.servlet.http.HttpServletResponseWrapper

Buffer an HTTP response to the file system, rather than streaming directly to the HTTP caller. This is useful for intermediary transformations without utilizing much heap, at the cost of some file IO.
