I’ve been reading about the cache_peer parameters and I add this line: cache_peer proxytest.com parent 3128 7 no-query login=PASS I thought that the login=PASS option would force squid to transfer all the authentications credentials to the next hop proxy, but I have the same behavior. the packets arrive with the Proxy_Authorization header but leave with out it. Any ideas to move on this issue?
