Step

(Optional)
If

you

are

using

the

ACE

appliance

(all

versions)

or

ACE

module

version

A4(1.0)

and

later,
in
the

Compression

Method

field,

choose

the

HTTP

compression

method

to

indicate

how

the

ACE
appliance
is

to

compress

packets

when

a

client

request

indicates

that

the

client

browser

is

capable

of
packet
compression.
By
default,

HTTP

compression

is

di

sabled

i

n

the

ACE.

When

you

configure

HTTP

compression

usi

ng
the
ACE,

the

appliance

compresses

data

in

the

HTTP

GET

responses

from

the

real

servers.

The

ACE
does
not

compress

HTTP

requests

from

clients

or

the

HTTP

headers

in

the

server

responses.
Note
By
default,

the

ACE

appliance

supports

HTTP

compression

at

rates

of

100

megabits

per

second
(Mbps).
Installing

an

optional

HTTP

compression

license

allows

you

to

increase

this

value

to

a
maximum
of

2

Gbps.
