------------------------------------------------------------
Seems that adding ;http.header.Connection=close to the end of the connect
string has helped but I also made a code change.
I'll try without the code change and lookup exactly what that header is doing.
So, It looks like setting Connection to close on the client is indicating that
the connection should be closed by the server. This is less than ideal but
performance seems to be pretty acceptable in my testing so far.
