How to configure squid to forward all traffic to another server

Add the below lines in the Squid.conf file
# assign internal network
 

acl our_networks src 10.0.0.0/8 192.168.1.0/24 192.168.2.0/24

http_access allow our_networks

http_access allow intranet

##----------Added for Forwarding to Another Proxy ------------##

cache_peer 10.10.1.20 parent 4444 0 no-query default

never_direct allow our_networks

Here 10.10.1.20 is the another proxy server which is working on 4444 port and the proxy will forward all traffic except internal to it
