well, in my opinion, using acls such as below should work :
acl type_xxx url_reg \?type=xxx
acl type_yyy url_reg \?type=yyy

What confuses me below is that most of those ACLs try to match "xxx" in
the path and not in the query string as in the example above. You can't
use any path_* acls to match a query string because the path stops before
the question mark.
