Re: High Volume Results Management

Keep in mind that the chunking option is 
automatic if you use the Pegasus clients and 
server.  But Pegasus attaches a trailer if there 
are errors in the response so that you client 
needs to understand this trailer to see if errors 
occur.  However, today that trailier is 
understood only by the Pegasus and som IBM client code.
