Varnish or Squid as cache server with IIS

Can we setup a Varnish or Squid server as web cache server for IIS server?

I开发者_JAVA百科 did not find much information anywhere. Please let me know where can I get information

Of course you can! You probably found the varnish and squid web sites and googled for some tutorials as a starting point. The question is; what do you want to cache? How is your website (not) cachable? Are you comfortable with linux (varnish only works on unix/linux/posix systems)? Why not stick with some Microsoft cache solution if you run IIS?
