[squid-users] Squid configuration cache_peer does not take effect?

The configuration is as follows:

```shell
# Squid normally listens to port 3128
always_direct allow all
ssl_bump bump all
sslproxy_cert_error allow all
http_port 3128 ssl-bump cert=/etc/squid/squid.pem key=/etc/squid/squid.pem
generate-host-certificates=on options=NO_SSLv2
#http_port 3128

cache_peer 127.0.0.1 parent 10809 0 no-query
never_direct allow all
```

I tested it and found out that the `127.0.0.1:10809` proxy was not taken?

How to solve? 

However, when I changed it to the following, it worked. But then Squid
cannot cache https.

```shell
http_port 3128

cache_peer 127.0.0.1 parent 10809 0 no-query
never_direct allow all
```

Why is that?
