Don't you think limiting the bandwidth per user with delay pools would be better
(more fair)...?
But if you really want to limit the number of users, maybe you could use an
external acl that will take note of the src IPs (with a given ttl, so no ttl on
the squid side).
If at a given time your list of IPs includes more than 20 IPs (different than
the current one), deny...
Those IPs will be taken off the list when they reach their ttl.
You could implement a fifo stream so that when the first IP is taken out, the
21th becomes the 20th and is accepted...
But that means they might receive only half of their webpage if the ttl expire
in the middle...
So you could reset the ttl of an IP at each connection...
But, with this setup, these 20 users could block others access forever if they
are really active...
Anyway, I do not think it is a good idea...
