Abstract
Controlling of a three-way handshake by a proxy server, while using dual-stack process. The proxy server is coupled between a plurality of surfer-equipment (SEs) and a plurality of webservers over IPv4 and/or IPv6 networks. The proxy server can obtain from a first SE, over the IPv6 network a first SYN packet that requests to establish a TCP connection over IPv6 with a first webserver. Next, the proxy server may check a list-of-webservers and determine whether a connection between the proxy-server and the first webserver over IPv6 will be established successfully. Accordingly, the server can determine whether to send a first SYN-ACK packet toward the first SE and send a second SYN packet over IPv6 toward the first webserver, or, to send the second SYN request over IPv4 toward the first webserver.
