Cannot deal with common buggy POST from applets

           Summary: Cannot deal with common buggy POST from applets
           Product: Tomcat 3
           Version: 3.3 Final
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Servlet
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: olaf.jahn@zamioculcas.net


Tomcat 3.3a cannot deal with wrong Content-Length POST requests
generated by common applet VMs. This was not a problem in Tomcat 3.2
(perhaps it did not do keep-alive, did it?)

The Java implementations contained in at least NS 4.7 (Linux + Win)
and IE 5.5 show the following behaviour:

When POSTing via (Http)URLConnection they append on or two bytes of
CR/LF without adjusting the Content-Length. Although Tomcat is
able to recognize the following requests coming over the same TCP/IP
connection it gets confused with their bodies: With (almost) every 
subsequent request the body read from request.getInputStream() contains 
more and more bytes left over from the previous request.
