refresh_pattern options don't work

["Aurélien Bras" <aurelien.bras@xxxxxxxxx>]

Hello,

When i add this in my squid.conf :

refresh_pattern .   0       20% 4320 override_expire

I have this error message :

redreshAddToList: Unknown option '.': override_expire

With this line :

refresh_pattern .   0   20% 4320 reload_into_ims

Same think, I have this error :

redreshAddToList: Unknown option '.': reload_into_ims

I use Squid Version 2.5.STABLE7, i have the same problem with 2.5.STABLE12.

Should I activate some stuff to activate these options ?

Thanks for your answers.

Aurélien.
