HTTPClient
Class SocksClient

java.lang.Object
  HTTPClient.SocksClient

All Implemented Interfaces:: GlobalConstants

class SocksClient
extends java.lang.Object
implements GlobalConstants

This class implements a SOCKS Client. Supports both versions 4 and 5. GSSAPI however is not yet implemented.

Usage is as follows: somewhere in the initialization code (and before the first socket creation call) create a SocksClient instance. Then replace each socket creation call sock = new Socket(host, port); with sock = socks_client.getSocket(host, port); (where socks_client is the above created SocksClient instance). That's all.

Version:: 0.3-2 18/06/1999

Constructor Detail

SocksClient

SocksClient(java.lang.String host,
            int port)

Creates a new SOCKS Client using the specified host and port for the server. Will try to establish the SOCKS version used when establishing the first connection.

SocksClient

            int port,
            int version)
      throws SocksException
