[squid-users] Squid through another proxy.

[Ordinary Man]

Dear all,
I have set up squid to use another proxy by inserting the following lines 
into the squid.conf file...
      cache_peer 10.0.0.27 parent 8080 0 no-query
      prefer_direct off

I expect this to use other proxy i.e.10.0.0.27 unless it is down in whcih 
case it can choose an alternative. however what squid does is that it sends 
some requests to 10.0.0.27 and some directly. Could anyone kindly eplain why 
squid si doing this?

if i use
       cache_peer 10.0.0.27  parent 8080  0 no-query default
       acl all_r src 0.0.0.0/0.0.0.0
       never_direct allow all_r
then squid works only through the other proxy...

what i want to do is to tell squid to use another route if and only if the 
10.0.0.27 proxy is down or is up but can't furnish requests and results in 
time outs....

awaiting response.
thanks in advance.
Toru.
