6-6 Px Series Application Switch Installation and Configuration Guide

Figure 6-2: Self-identifying cookie persistence mode

The following transactions occur in Figure 6-2:

• The website administrator of www.buystuff.com sets up each web server (server 1,

server 2, and server 3) to create a cookie that contains the real IP address of the web

server.

— Cookies created by server 1 contain IP address 10.1.1.1.

— Cookies created by server 2 contain IP address 10.1.1.2.

— Cookies created by server 3 contain IP address 10.1.1.3.

• The website administrator configures the Px series application switch to use

self-identifying cookie persistence mode.

• The client transmits its first TCP request (A) to www.buystuff.com at its

publicly-known VIP address, 64.1.1.7.

• The Px series application switch responds (B) on behalf of 64.1.1.7, and the three-way

TCP handshake is established between the client and the Px series application

switch.
