Following Henrik's instructions, I downloaded 2.6 version 13 stable and installed it on a Red Hat Linux box. I then updated the configuration file with the following changes: # Port 80 is being used so changing to 8080. If this was a production box, # I would use port 80 here. http_port 8080 accel defaultsite=googleapp2o.ismc.intelink.gov # 172.16.7.199 (googleapp1o) # 172.16.7.200 (googleapp2o) cache_peer 172.16.7.200 parent 80 0 no-query originserver name=googleapp proxy-only cache_peer 172.16.10.36 parent 80 0 no-query originserver name=solgoogle proxy-only acl bin urlpath_regex ^/cgi-bin/ cache_peer_access solgoogle allow bin cache_peer_access googleapp deny bin # Was suggested for 2.5 and suggested for 2.6 never_direct allow all Now when I go to http://lindev2o.lab.ismc.intelink.gov:8080/, I get an access denied when trying to retrieve http://googleapp2o.ismc.intelink.gov/ Also when I got to http://lindev2o.lab.ismc.intelink.gov:8080/cgi-bin/GoogleDiagnostics.pl, I get the same access denied message and it looks like squid is trying http://googleapp2o.ismc.intelink.gov/cgi-bin/GoogleDiagnostics.pl instead of http://lindev2o.lab.ismc.intelink.gov/cgi-bin/GoogleDiagnostics.pl I did a wget http://googleapp2o.ismc.intelink.gov/ from the lindev2o box and was able to fetch the page with no problems. tail -f ../var/logs/access.log shows "TCP_DENIED/403" error messages. I will continue to look over the configuration file and read the Wiki. Any suggestions would be appreciated. Jake
