Filter that delegates JSP worked in ver 4.1.12 and not in 4.1.18

           Summary: Filter that delegates JSP worked in ver 4.1.12 and not
                    in 4.1.18
           Product: Tomcat 4
           Version: 4.1.18
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: paulosimao@ieg.com.br


A Filter developed to work as decorator was wotking in version 4.1.12. I builds 
a previous and post content in a page, delegating via RequestDispatcher the 
processing of pre and pos components (JSP pages) and then stores it in a 
buffer. Later it forwards to the main page, to complete de request, and append 
pre before te page contents and pos after. It all is buffered in server before 
sending to client. To complete this task I implemented an HttpServletResponse 
that "fools" the container, that wrapps the original one and buffers it's 
contents. It worked really fine in 4.1.2, but in 4.1.18 it doesn't work, a 
small part of the final content is sent to the client, what makes think that it 
has some thing related to the buffering sub-system in Tomcat.
