Cannot add responses headers in filter after doFilter

           Summary: Cannot add responses headers in filter after doFilter
           Product: Tomcat 5
           Version: 5.0.14
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Connector:Coyote
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: kevinj@develop.com


I have a very simple filter that calls response.addHeader both before and after
calling chain.doFilter. Before chaining the header is added, after chaining the
header is not added. Also I cannot set the value of the header after chaining,
or set a cookie.

To see this failure

Try this, browse to http://localhost:8080/index.jsp. For the page itself I see a
200 response and all my headers being set. For the gifs I get a 200 but only the
headers I set *before* calling chain.doFilter are set. If I then refresh I get a
304 Not Modified response (for the gifs) from tomcat and all the headers are set!
