aggressive cache

i want to aggressively cache as much information as possible.

i realize some page web pages have a no-cache policy so the web proxy ends up giving me a MISS and a NO hit according to the log.

heres my current configuration:

[admin@GrnZne-Net] ip web-proxy cache> print
Flags: X - disabled, I - invalid 
 0 X ;;; don't cache dynamic http pages
     url=":cgi-bin \\?" action=deny 

 1   ;;; cache all
     action=allow 
[admin@GrnZne-Net] ip web-proxy cache> ..
[admin@GrnZne-Net] ip web-proxy> print
                 enabled: yes
             src-address: 0.0.0.0
                    port: 3128,8080
                hostname: "proxy"
       transparent-proxy: yes
            parent-proxy: 0.0.0.0:0
     cache-administrator: "ahmad"
         max-object-size: 512000KiB
             cache-drive: system
          max-cache-size: unlimited
      max-ram-cache-size: unlimited
                  status: running
      reserved-for-cache: 28609536KiB
  reserved-for-ram-cache: 2048KiB
[admin@GrnZne-Net] ip web-proxy>

please advise.

anyone?
