This is the latest support squid-2 version for RHEL5.3 An I want to use the dnsserver -----Ursprüngliche Nachricht----- Von: adrian.chadd@xxxxxxxxx [mailto:adrian.chadd@xxxxxxxxx] Im Auftrag von Adrian Chadd Gesendet: Dienstag, 14. Juli 2009 10:38 An: Jarosch, Ralph Betreff: Re: https from different Subnet not working The first thing you should do is upgrade to the latest Squid-2 or Squid-3, depending upon your environment needs. Secondly, you should evaluate whether you truely want to use dnsserver, or whether you can use the internal DNS redirector.
