Parameters:

urlConnection - a reference to a URLConnection.

localHost

public static java.lang.String localHost()

local host address (parse out only IP address)

Returns:

getAllInetAddressesForLocalhost

public static java.net.InetAddress[] getAllInetAddressesForLocalhost()

wrapSingleAddress

public static final java.net.InetAddress[] wrapSingleAddress(java.net.InetAddress address)
