How to correctly configure squid to work with the parent proxy?

Question

Squid

Current config:

http_access allow all
never_direct allow all
 
forwarded_for off
via off
follow_x_forwarded_for deny all
request_header_access X-Forwarded-For deny all
 
http_port 9000 name=fifteenFirst
acl fifteenFirst myport 9000
cache_peer 63.141.241.98 parent 16001 0 proxy-only no-query
cache_peer_access 63.141.241.98 deny !fifteenFirst

The proxy works, but from time to time there are errors in chrome ERR_EMPTY_RESPONSE. Reloading the page several times helps. A line like this appears in the access log:

TAG_NONE/000 0 CONNECT www.intelius.com:443 - FIRSTUP_PARENT/63.141.241.98

or

TCP_MISS/301 219 GET http://intelius.com/ - FIRSTUP_PARENT/63.141.241.98

What could be causing this and how can it be resolved?

Answer 1

The problem turned out to be bad proxies. config is correct
