just a sec.
i copied the code damn wrong from squid.conf (early hours of the morning)
it is as you say:
external_acl_type rrselector ttl=0 negative_ttl=0 grace=0
children-startup=1 children-max=1 %URI /somedir/script.sh

but what can be done?
means if it's a fast and so.. i will might need to do some early use of
the acl with some caching?
what mean is like run any use of this specific acl rrs on let say

http_access allow rrs dummy_acl_that_will_be_never_matched

Thanks,
Eliezer
