Documents are transmitted twice when calling via POST from external source

           Summary: Documents are transmitted twice when calling via POST
                    from external source
           Product: Tomcat 4
           Version: 4.1.12
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: johann.uhrmann@xpecto.com


The following configuration makes tomcat (or the http-Connector?) transmit
the document (html page or jsp) twice. 
This causes the page to be shown twice on the client:

- An external site (not hosted on tomcat) has a form which is sent via
  POST on a tomcat page.

- The document on the tomcat server is the index document for that web 
  application.

- There is a filter for that web application which reads the parameters given
  by the post request and sets some session parameters and a cookie.
  It also wraps the request to overload getRemoteUser and isUserInRole.
  (That filter is actually used for single-sign-on authentication.)

- The referring site is hosted on the same machine, but on an Apache web server:
  http://www/apostform.html --[http-post]---> http://www:8081/myapp/index.jsp


According to tcpdump, the page is transmitted twice as a reply for a single
post request. The reply is also transmitted in a single packet (if it's small
enough) which may indicate that the output buffers on tomcat have nut been flushed.
