Trailing CRLF on POSTs
This is a legacy issue. The CERN webserver required POST
data to have an extra CRLF following it. Thus many
clients send an extra CRLF that is not included in the
Content-Length of the request. Apache works around this
problem by eating any empty lines which appear before a
request.
"
Boa will (for now) hack around this stupid bug in Netscape
(and Internet Exploder)
by reading up to 32k after the connection is all but closed.
This should eliminate any remaining spurious crlf sent
by the client.
Building bugs *into* software to be compatible is
just plain wrong
