Actually, I was meaning `method version', skipping the URI entirely of
`method URI version'.  I'm not concerned about meeting any HTTP
standards as the configuration would negate any capability of
processing HTTP protocol.  The server would be dedicated to responding
to two types of requests but those would be part of a Keepalive
connection so I'm only concerned about the being able to receive the
full compliment of header information on the connection request.
Further input later on would off load a request to a `C' program to
process while the server keeps the connection open sending poll
messages to the requester until there is actual data to return.  Only
then would the connection be dropped.

Mod_perl handlers appear to give me the functionality I need to
process requests after the initial connection while apache supplies
the socket handling to respond to multiple (session) requests if
needed.  I will modify the apache source if that it what is required
but it would appear the mod_perl handlers should be able to give me
all the capability that I would need to manipulate with the apache
API.
