Hello,

I am using Polipo with Tor. Therefore I have been using the polipo.conf 
file from 
https://svn.torproject.org/svn/torbrowser/trunk/build-scripts/config/polipo.conf
 


I am using:

socksParentProxy = "localhost:9050"
socksProxyType = socks5

However, I do not understand this part:

# Uncomment this to disable Polipo's DNS resolver and use the system's
# default resolver instead. If you do that, Polipo will freeze during
# every DNS query:

dnsUseGethostbyname = yes

Section 3.9 of the Polipo manual says:

Polipo usually tries to speak the DNS protocol itself rather than using 
the system re-
solver5 . Its precise behaviour is controlled by the value of 
dnsUseGethostbyname. If
dnsUseGethostbyname is false, Polipo never uses the system resolver. If 
it is reluctantly
(the default), Polipo tries to speak DNS and falls back to the system 
resolver if a name server
could not be contacted. If it is happily, Polipo tries to speak DNS, and 
falls back to the system
resolver if the host couldn’t be found for any reason (this is not a 
good idea for shared proxies).
Finally, if dnsUseGethostbyname is true, Polipo never tries to speak DNS 
itself and uses the
system resolver straight away (this is not recommended).

1. Since "yes" is not one of the four options listed, what does "yes" 
mean? Why is this in the config file? I have posted to the Tor list with 
no response.

2. I always use Polipo with Tor. My understanding (tell me if I am 
wrong) is that Polipo passes DNS requests on to Tor which resolves them 
at the final exit node. Therefore, does it matter what is set for 
dnsUseGethostbyname (even if it is something like "true" or 
"reluctantly" which exist) since the socksParentProxy takes precedence 
and all DNS requests are automatically passed to Tor?

Thanks - much appreciated.
