Enable
Insert
Check
box

that

determines

if

the

virtual

server

is

to

insert

a

cookie

in

the

Set-Cookie

header

of

the
response
from

the

server

to

the

client.

This

option

is

useful

when

you

want

to

use

a

session

cookie
for
persistence

but

the

server

is

not

currently

setting

the

appropriate

cookie.

When

selected,

the
virtual
server

selects

a

cookie

value

that

identifies

the

original

server

from

which

the

client

received
a
response.

For

subsequent

connections

of

the

uses

the
