Delay pools (throttling) for specified websites?

[D & E Radel <radel@xxxxxxxxxxx>]

Hi all,

I am currently using a delay pool to throttle users a certain ldap_group to a slow speed.

I wish to throttle access to certain bandwidth heavy websites. I added the ACL "slow_sites" to my 
existing delay pool as follows:

    acl slow_sites url_regex -i "/squid_stuff/slow_sites.txt"

    # Delay pools
    #-------------------------------------------------
    delay_pools 1
    delay_class 1 3
    delay_access 1 allow slow_group slow_sites
    delay_access 1 deny all
    delay_parameters 1 250000/250000 -1/-1 8000/250000

It didn't slow down access to the sites listed in the textfile. Whereas, the delay pool was already 
working correctly on the users in slow_group before my adjustments.

Any help greatly appreciated. Many thanks in advance.
D.Radel.
