Cache
Forward
Field
that

specifies

how

the

ACE

appliance

is

to

implement

cache

forwarding:

•
N/A—This
feature

is
not
enabled.

•
With
Wait—Cache

forwarding

is

enabled

with

the
wait
option

for
the
specified

URLs.

If

the

object
has
expired

but

the

maximum

cache

TTL

time

period

has

not

yet

expired,

the

ACE

appliance

sends
a
request

to

the

origin

server

for

the

object.

Users

requesting

this

page

continue

to

receive

content
from
the

cache

during

this

time

but

must

wait

for

the

object

t

o

be

updated

before

their

request

is
satisfied.
When

the

fresh

object

is

returned,

it

is

sent

to

the

requesting

user

and

the

cache

is

updated.

•
Without
Wait—Cache

forwarding

is

enabled

without
the
wait
option.

that

specifies

that

the

ACE

appliance

is

to

implement

just-in-time

object

acceleration
for
embedded
objects

not

able

to

be

cached.

This

feature

enables

the

acceleration

of

embedded

objects

not
able
to

be

cached,

which

results

in

improved

application

response

time.

When

enabled,

this

feature
eliminates
the

need

for

users

to

download

objects

not

able

to

be

cached

on

each

request.
