question: FtpURLConnection ( URL url , Proxy p ) { super ( url ) ; instProxy = p ; host = url . getHost ( ) ; port = url . getPort ( ) ; String userInfo = url . getUserInfo ( ) ; if ( userInfo != null ) { int delimiter = userInfo . indexOf ( ':' ) ; if ( delimiter == - 1 ) { user = ParseUtil . decode ( userInfo ) ; password = null ; } else { user = ParseUtil . decode ( userInfo . substring ( 0 , delimiter ++ ) ) ; password = ParseUtil . decode ( userInfo . substring ( delimiter ) ) ; } } }
target:  Same as FtpURLconnection(URL) with a per connection proxy specified
