UTF-8

UTF-8

(8-bit

Format)

character

set,

which

is

an

international

standard

that

allows

Web

pages

to

display

non-ASCII

or

non-English

multibyte

characters.

It

can

represent

any

g

e

r

(

%)

Server

load

threshold

trigger

that

indicates

that

the

time-to-live

(TTL)

period

for

cached

objects

is

to

be

based

dynamically

on

server

load.

With

this

method,

TTL

periods

increase

if

the

current

response

time

from

the

origin

sever

is

greater

than

the

average

response

time

and

decrease

if

the

current

response

from

the

origin

server

is

less

than

the

average

response

time

when

the

difference

in

response

times

exceeds

a

specified

threshold

amount.

Enter

the

threshold,

expressed

as

a

percent,

at

which

the

TTL

for

cached

objects

is

to

be

changed.

Valid

entries

are

from

0

100

percent.
