[squid-users] caching problem

[Mohammad Fattahian]

Hi,

I have a caching problem.

I want to redirect my traffic to other Proxy server.

       cache_peer ip_address       parent    8090  0   no-query    default
       acl all src 0.0.0.0/0.0.0.0
       prefer_direct off

With this setting sometimes I saw the old pages, but without this the pages
are up-to-dated.

How can I flush cache of the parent proxy sever?
And why do I have this problem?

Mohammad
