MaxMessageSizeExceededException in weblogic how to solve

Question

How to solve this Exception. When is sent more than 8000 bytes of data
in the request weblogic 5.1 in solaris server gives me this error. But
the same server and same configuration in Window NT with same
SSLClient program does not give any expection even if i send 60000
bytes in the request.
Exception got in the weblogic server 5.1 in solaris server
weblogic.socket.MaxMessageSizeExceededException: [Incoming HTTP
request headers of size 8320 bytes exceeds the configured maximum of
8192 bytes]

Hello
I had taken a crack at this before but never got a response --
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.security&item=6948&utag=
Can you look at my old post and see if that helps at all? Please let me know
