[squid-users] 503 service unavailable on connection refused

[Dominic Kim]

My bad..

Please find the attached log.

It looks squid is retrying many times.
And after reach maximum retry limit, it responds with 503 service
unavailable.

As you know maximum limit is 10 times.
It looks that it retries 10 times within just 3 seconds.

Are there any way to configure retry interval?

Thanks
Regards
Dominic
