Optimization
Overview
The
application

acceleration

functions

of

the

ACE

appliance

apply

several

optimization

technologies

to
accelerate
application

performance.

This

functionality

enables

enterprises

to

optimize

network
performance
and

improve

access

to

critical

business

information.
The
ACE

appliance

provides

the

following

application

acceleration

and

optimization

functionality:

•
Delta
optimization

eliminates

redundant

traffic

on

the

network
by
computing

and
transmitting
only
the
changes

that

occur

in

a

Web

page

between

successive

downloads

of

the

same

page

or

similar
pages.

•
FlashForward
object

acceleration

technology

eliminates

network

delays

associated

with

embedded
Web
objects

able

to

be

cached.

such

as

images,

style

sheets,

and

JavaScript

files

by

placing

the
responsibility
for

validating

object

freshness

on

the

ACE

appliance,

rather

than

on

the

client,

making
the
client

more

efficient.

•
Just-in-time
object

acceleration

enables

acceleration
of
non-cacheable

embedded

objects,
resulting
in
improved

application

response

time

by

eliminating

the

need

for

clients

to

download

these

objects
on
each

request.

•
Adaptive
dynamic

caching

accelerates

enterprise

application
performance

and

improves

server
system
scalability

by

enabling

the

ACE

appliance

itself

to

fulfill

requests

for

dynamic

content,
which
offloads

application

servers

and

databases.

and

Typical

Configuration

Flow
To
define

the

different

optimization

and

application

acceleration

functions

that

you

want

the

ACE
appliance
to

perform,

you

must

configure

at


least

one

each

of

t

he

following:

•
HTTP
optimization

action

list—This

action

list

specifies

the

actions

that

the

ACE

is

to

perform

for
application
acceleration

and

optimization.

You

can

configure

action

lists

when

configuring

a

virtual
server,
or

a

s

a

separate

pr

ocedure.
