acl to_server1 path_reg MSISDN/[0-9]+[0-3] acl to_server2 path_reg MSISDN/[0-9]+[4-6] acl to_server3 path_reg MSISDN/[0-9]+[7-9] use_backend server1 if to_server1 use_backend server2 if to_server2 use_backend server3 if to_server3 Depending on youa actual URL space, it could be sufficient to use this instead as the acls which would be faster as it does not involve any ACLs: acl to_server1 path_end 0 1 2 3 ...

It can not alter or check anything inside the HTTP body currently. You can only access inside the HTTP header section here. --Holger
