And the behavior were same.

Thanks

When I connect to a target server via squid, if server does not exist, I get "No route to host" error.

And if server exist, but port is not opened yet, I get "Connection refused" error.

As per the definition of "connect_retries" option, it should retry when connection attempt failed.

(reference: http://www.squid-cache.org/Doc/config/connect_retries/)

IMHO, in both the cases, connection attempts failed and it is supposed to retry.

However, if I enable this feature, it only retries on "No route to host" error.

In case of "Connection refused", I am getting 503 service unavailable error immediately.

Are there anyway to fix this behavior?

Kindly help me.

Thanks
