Can ISA be used for caching purpose only? Please note that we are using PIX firewall in our network. we tried to install ISA on a Win2000 member server (with AD) for caching purpose only. (ISA server has only one NIC) After installing ISA we found that the user request to Internet is reaching our ISA only. How & what should be configured in order that our ISA forward (routes) the http user browsing request to our ISP proxy. **Please note that the Internet should be accessed through the proxy server of our ISP. Please help, Thank you, Ziad
