    • Method Detail

      • connectSocket connectSocket​( sock,
                                      HttpParams params)
        Connects a socket to the target host with the given remote address.

        Please note that HttpInetSocketAddress class should be used in order to pass the target remote address along with the original HttpHost value used to resolve the address. The use of HttpInetSocketAddress can also ensure that no reverse DNS lookup will be performed if the target remote address was specified as an IP address.

        sock - the socket to connect, as obtained from createSocket. null indicates that a new socket should be created and connected.
        remoteAddress - the remote address to connect to.
        localAddress - the local address to bind the socket to, or null for any
        params - additional parameters for connecting
        the connected socket. The returned object may be different from the sock argument if this factory supports a layered protocol.
        Throws: - if an I/O error occurs - if the IP address of the target host can not be determined
        ConnectTimeoutException - if the socket cannot be connected within the time limit defined in the params

        boolean isSecure​( sock)
                  throws java.lang.IllegalArgumentException
        Checks whether a socket provides a secure connection. The socket must be connected by this factory. The factory will not perform I/O operations in this method.

        As a rule of thumb, plain sockets are not secure and TLS/SSL sockets are secure. However, there may be application specific deviations. For example, a plain socket to a host in the same intranet ("trusted zone") could be considered secure. On the other hand, a TLS/SSL socket could be considered insecure based on the cipher suite chosen for the connection.

        sock - the connected socket to check
        true if the connection of the socket should be considered secure, or false if it should not
        java.lang.IllegalArgumentException - if the argument is invalid, for example because it is not a connected socket or was created by a different socket factory. Note that socket factories are not required to check these conditions, they may simply return a default value when called with an invalid socket argument.
