use.
Server
Load
Time-To-Live
Change
(%)
Option
that

specifies

the

percentage

by

which

the

cache

TTL

is

increased

or

decreased

in

response
to
a

change

in

server

load.

For

example,

if

this

value

is

set

to

20

and

the

current

TTL

for

a

response
is
300

seconds.

and

if

the

current

server

response

times

exceeds

the

trigger

threshold,

the

cache
TTL
for


the

response

i

s

raised

to

360

seconds.
Enter
the

percent

by

which

the

cache

TTL

is

to

be

increased

or

decreased

when

the

server

load
threshold
trigger

is

met.
Valid
entries

are

from

0

to

100

percent.
Delta
Optimization
Mode
Method
by
which
delta

optimization

is

to
be
implemented.
The
choices

are

as

follows:

•
N/A—This
option

is
not
configured.

•
Enable
The

All-User

Mode

For

Delta

Optimization—The

ACE

is

t

o

generate
the

delta
against
a

single

base

file

that

is

shared

by

all

users

of

the

URL.

This

option

is

usable

in

most
cases
if

the

structure

of

a

page

is

common

across

all

users,

and

the

disk

space

overhead

is
minimal.

•
Enable
The

Per-User

Mode

For

Delta

Optimization—The

ACE

is

to

generate

the

delta
against
a

base

file

that

is

created

specifically

for

that

user.

This

option

is

useful

when

page
contents,
including

layout

elements,

are

different

for

each

user,

and

delivers

the

highest

level
of
condensation.

However,

this

increases

disk

space

requirements

because

a

copy

of

the

base
page
that

is

delivered

to

each

user

is

cached.

This

option

is

useful

when

privacy

is

required
because
base

pages

are

not

shared

among

users.
