[squid-users] Squid 5 does not send ICAP request

[橋本紘希]

I made squid and ICAP system using docker-compose.

Squid 4 started sending ICAP requests 1 minute after boot.

However, squid 5 sends no ICAP request even 10 minutes after boot.
Squid continued to mark the ICAP service down.

How can I make squid 5 to start ICAP conversation?

* squid version
5.0.5-20210223-r4af19cc24

* squid.conf

```
http_port 3128
http_access allow all
icap_enable on
icap_service icapsvc reqmod_precache icap://icap5:1344 bypass=off
adaptation_access icapsvc allow all
icap_persistent_connections off
icap_service_revival_delay 60
debug_options ALL,9
```

* This is my environment.

* I uploaded access.log and cache.log to the GitHub issue.
