Re: Http Connection Pooling in Camel

If you don’t setup the ConnectionManager on the Http4Component, Camel just 
create a new Connection which is based on the setting of maxTotalConnections 
and connectionsPerRoute.

I haven’t used this component very much, but the documentation 
(http://camel.apache.org/http4.html ) seems 
to hint at some sort of persistent connections (i.e. maxTotalConnections, 
connectionsPerRoute, etc).
