This is a parent relation with the default option, and with the origin server as secondary parent without the default option. sibling relations only borrow already cached material. You can not ask a sibling to do stuff for you, only give you copies of what it already has. This is the main difference between a sibling and parent relation. > In future I want to purchase more VPS servers and create a little > cluster where squid1 acts as main node and uses round robin to kind of > load balance server load.
