Litespeed cache settings

[rosaline]

I use Litespeed Enterprise edition on our dedicated WHM panel.

When I test my site with pingdom in this link :http://tools.pingdom.com/fpt/

At request header's part: it says pragma: no-cache and cache-control is no-cache.. But response header's part is normal.

I am sending screenshot of my cache settings in attachment. I have enabled cache on admin panel of Litespeed and configured some values as like:

Expire default value is:A3600

Expire by types: text/css=A604800, text/javascript=A604800, application/javascript=A604800, application/x-javascript=A604800, application/x-shockwave-flash=A604800, image/gif=A604800, image/jpg=A604800, image/jpeg=A604800, image/png=A604800, image/ico=A604800, image/icon=A604800

Did I make any mistake from somewhere?
