Re:Re:Re: What is the meaning and function of ping_status?

Thanks, Henrik pal!

I search "ping" in peer_select.c, FAQ and squid.conf.
And find it is used to meansure the RTT time of the
origin server. We often use it to select ICP peers.
I find there are such PING_STATUS,
PING_NONE, PING_WAITING.

After reading the related codes, I think PING_NONE means
we do not use the ping mechanism or the ping event is not
doing now. But I am not very sure about it. Am I correct?
Can you give me a simple explanation?

I think PING_WAITING means our cache is doing the ping
event to measure the origin server and the RTT time of
ICP peers. But I am not very sure about it. Am I correct?
Can you give me a simple explanation?

Best regards,
George Ma
