Hello Amos,
thanks for your suggestion.
I removed "originserver" from my config.
Still I see the requests answered by my own squid and not relayed over the cache_peer.

I'm limited with providing my squid configuration - I can't provide the config to hole
audience due to security restrictions.
Tell me which squid config details you like to have and I see what i can do.
