More flexible caching option?

["howard chen" <howachen@xxxxxxxxx>]

Hi,

I use squid as a HTTP accelerator for my web servers for serving images files.

I want to know if it is possible, say, do the caching for my image
files ONLY if more than 10 clients request for this file, otherwise,
pass it thru to the web server.

i.e. for the first 10 hits, don't cache => pass to the web server



Any rules like this an be specified?

Thanks.

Howard
