+-- server1(a.jpg)

client -- CSS --+

+-- server2(b.jpg)
1) establish the connection between client and CSS(vip:192.168.74.100)
2) send 'GET /a.jpg' from client
3) send 'GET /b.jpg' from client
If client sends above requests in order and 'persistence reset remap' is enabled,
CSS sends first get request(GET /a.jpg) to server1. After 2nd get request is received
from client, CSS sends RST to server1 and then establishes connection with server2
to get b.jpg.
