Hi People ; Thanks for your reply , thanks to Adrain Chadds tips . I edited the init script & changed the squid user to root , now its working for port 80 , I would like to clarify the following Three questions Question 1 ) Is there any security issues for running squid as root ? I am setting up my squid as http accelerator , so squid will handle the request first , then handed over it to Apache (which is now Listen on 81) then from Apache to my zope(which is on port :8080) so what I added in squid is http_prot 80 accel vhost cache_peer 127.0.0.1 parent 81 0 originserver default http_access allow from all ############## my apache Listen on 81 and the vhost entry for my site is like this NameVirtualHost *:81 <VirtualHost *:81> RewriteEngine On RewriteRule ^/(.*) http://127.0.0.1:8080/VirtualHostBase/http/demo.mysite.net:81/mysite/VirtualHostRoot/$1 [L,P] ErrorLog /var/log/apache/demo.mysite.net/error_log CustomLog /var/log/apache/demo.mysite.net/access.log combined </VirtualHost> Previously This site was too slow when I use apache infront of zope , so all request is coming to apche then apache Rewrite rule will hand over the request to zope:8080 Now in the new setup squid is infront , question 2 ) how can I check to make sure the squid is handling all the request first , and so its performance as an http accelerator ? question 3) I have a number of VirtualHost (name based) entries in my apache , so running the sqid in front on port :80 , did accelerate the speed of my vhost sites ? Looking for your valuable comments on this setup , I am looking for the pros/cons of this setup squid-->apache--> applications Thanks in advance for your valuable feedback as early as possible KK
