DataInputStream readLong() Problem

           Summary: DataInputStream readLong() Problem
           Product: Apache httpd-1.3
           Version: 1.3.24
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Content-type
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: pauric.cregg@spectel.com

Configuration - Apache 1.3.24, AJP13, Tomcat 4.0.3

When doing a post request from an applet to a servlet via Apache, the DataInputStream.readLong() value does not appear to be read correctly.

In order to test this I have created a testClient and testServlet the code for which is included below plus the output I received when I ran the tests.

If I test against Tomcat directly everything works fine. If the request is routed via Apache first the values appear to be corrupted. Below is the output I receive from the test program.

Does anybody have any idea why the example code below does not work on Apache ?

>From what I understand it should work and appears to work fine when using
Tomcat directly. If anybody can help it would be much appreciated.

best regards
Pauric
