You may be able to limit the establishing connection dialog by changing the "idle timeout" in network preferences. If I'm doing a lot of retrievals I change the timeout to close the connection on power off.
If you suspect that the HTTP connection class is taking up time you can try simply opening a socket to your server and sending the line "GET filename" to see if it is any faster.
The http connection may also be doing a dns lookup every time that is slowing it down. You could do a gethostbyname then cache the ip address for the above mention socket connection.

That is probably the problem and appears to be what is going on.
I am trying to avoid the long "establishing connection" period on the
wireless...this could be a problem.
But thanks - Your statement has helped back up my assumptions.
They have an undocumented class called HTTPSession that I am exploring
now, it seems to be nothing more than a link list of httpconnections!
