Hello Squid Users I am in need of some help. I believe this must have been done by some already but i could not just get the right document to understand well. Setup : Squid v3.2.3 on a RHEL 6 64-bit VM (say server1) Apache's 2.2.15 on RHEL6 64-bit VM's (running in server1 and in server2). Requirement: 1. All http traffic should automatically redirect to https without a change in the url (except http -> https ) 2. I have two URL's A.B.C.D and A.C.D both pointing to the server1 IP must work well. 3. When Apache in server1 dies, all traffic should work well with Apache in server2. All traffic must use Squid for ReverseProxy/Cacheing What i have done so far ? 1. Apache V-hosts (8080 & 443 ) : 8080 V-hosts does RewriteRule to https 2. Squid listens in 80 and 3123 (for ssl) having these entries in its config. https_port 3128 accel cert=/usr/local/apache2/conf/folder/certnew.cer key=/usr/local/apache2/conf/folder/a.b.c.d.key defaultsite=a.b.c.d vhost http_port 80 accel defaultsite=a.b.c.d vhost cache_peer server1.b.c.d parent 8080 0 originserver round-robin cache_peer server2.b.c.d parent 8080 0 originserver round-robin What i understand is, requests coming to Port 80 (Squid) forwarded to either of Apache's 8080 where it gets rewritten to 443, processed. This works well when both Apache's are running fine. When i bring down Apache1, It breaks. Apache2 up/down does not make a difference as i noticed though they are effectively used when both in running state as i noticed from their logs. So it looks like they do effective load-balancing in normal state, but cant take Apache1 from its critical path. Can you guys help me understand how i set this up ? I'm not sure the http->https redirect must be done by Apache or the Squid or using any redirector.pl within Squid. Which works best/faster ? Any help or reference doc / config would be much appreciated. I dont have a requirement for people directly coming to server1 or server2 to either of its 8080/443 ports. All traffic to be routed through the domain url's "a.b.c.d" or "a.c.d" ONLY. Thanks a lot.
