This code was from the days when keepalives were supported, but there 
was no connection pool, so keeping the connection open beyond the end of 
a frontend connection made no sense.

Now there is a connection pool, so in theory the code should no longer 
be there. I would check though whether removing this code (which I think 
is the right thing to do) doesn't uncover some regressions - the major 
testing on the connection pool as I understand revolved around the ajp 
connector rather than the http connector.
