Seams that the minotaur is behaving badly, so I'm getting mails with couple of hours delay :)

I'll make a generic obtain_connection that will be pulled out from the worker (connection pool), with opened socket (if closed). The way how it gets processed further depends on how the scheme handler says. For http connector the connection will be bound to the client connection. It will be returned to the pool (and closing the socket) when their connection id's are different. I have to see how to resolve the case when client breaks the connection. any ideas? For ajp connector the connection will be returned to the pool on request end (AJP can handle different clients trough the same socket). The ftp will probably call 'login' for new connections, but I'll first finish the upper two cases, and deal with ftp later (couple of days :) MT.
