WebConnectionPlus

UT2003 :: Object >> Actor >> Info >> InternetInfo >> InternetLink >> TcpLink >> WebConnection >> WebConnectionPlus (Ladder1.46)

This functionality provided by this class (keeping the connection open after a query()) will be integrated into UT2003 as of the next patch, so this class will no longer be necessary.
