Is what follows the output from the client or from the server?  I would 
like to see both if possible.  Run the web100clt with -dddddd and 
web100srv with -dddddd (6 d's each - maximum debugging).

This is the first area we need to see more about, this looks like client 
output.  We need to see what the server is sending to cause this.

This is the second area we need to see more about.  Try to run both with 
the debug options and send the output from both.
