Enterprise Edition, like Standard Edition, supports remote-access VPNs, including network quarantine control, and site-to-site VPNs. The added feature that is available in Enterprise Edition is the option to use NLB for VPN connections. When you enable NLB for an array and configure the array policy to enable remoteaccess VPNs, the VPN client must be configured to connect to the NLB shared IP address. When a remote access client initiates a VPN connection to an array, it initiates the connection on the shared IP address. One of the array members establishes the VPN connection and allocates an IP address for that client. From then on, that array member maintains the VPN connection, and all traffic for that remote client passes through that array member. As additional remote access VPN clients connect, the connections are distributed across all available ISA Server computers in the array. To enable NLB for site-to-site VPNs, the remote site network must be configured to connect to the shared IP address for the NLB cluster in the destination site. At the destination site, one of the ISA Server computers accepts the VPN connection and becomes the VPN gateway server for the site. If the source network is also configured for NLB, ISA Server automatically assigns one array member to handle the VPN tunnel. The VPN gateway server in each site will maintain the VPN tunnel. In this way, parallel tunnels between two sites are not created. Moreover, when a client on one network tries to access resources on another remote site network, the client request is automatically directed to the array member that is hosting the VPN connection. If the server that owns a site-to-site VPN connection fails, ISA Server automatically shifts the connection to another ISA Server array member. You can also enable site-to-site VPNs without integrating the VPN service and NLB. In this scenario, you must select the one of the array members as the ISA Server computer that will initiate the VPN connection to the remote site, and the remote-site ISA Server must be configured to use the specified ISA Server as the tunnel destination. This scenario does not provide any fault tolerance; if the server designated as the VPN tunnel owner fails, you must configure another ISA Server to manage the connection.

ISA Server provides distributed caching through the use of the Cache Array Routing Protocol (CARP). CARP distributes the cache used by Web Proxy clients across an array of ISA Server computers. CARP is used by Web browsers and by ISA Server to increase performance when accessing a Web site using a Web Proxy client. CARP uses hashbased routing to determine which ISA Server computer will respond to a client request and cache specific Web content.

CARP provides the following benefits:
CARP eliminates the duplication of cache contents across multiple ISA Server computers. The result is a faster response to queries and a more efficient use of server resources. Because CARP determines which ISA Server will cache any specific content, no traffic is required between ISA Server computers to determine which server is caching the content. CARP automatically adjusts when array members are added or removed. The hash-based routing means that when a server is either taken offline or added, only minimal reassignment of URL caches is required. CARP ensures that the cache objects are either distributed evenly between all servers in the array or by the load factor that you configure for each server.
How CARP Works
The CARP process provides efficient routing for Web requests on the client side and on the server side. When client-side CARP is enabled, the Web browser downloads the Array.dll Get.Routing.Script from an ISA Server computer in the array. When a user types a URL into a Web browser, the URL is submitted to the script, which calculates which ISA Server in the array will be used to cache the content. The script always returns the same server list for a given URL, ensuring that each URL is cached on one array server only. The script generated by ISA Server implements the CARP algorithm. The script includes information about the configuration and current status of the array. By default, the script ensures that the URL space is distributed evenly across the available ISA Server computers. You can also configure a load factor for each array member that allows you to distribute the cache based on server configuration. ISA Server also enables server-side CARP for Web clients that do not use client-side CARP. In this situation, when a client sends a Web request to an array member, the server runs the CARP script with the requested URL and determines the array member that can best serve the request. The request is forwarded to that server.
NLB can be used to load-balance all types of network traffic going into the array. When clients connect to an NLB cluster, they use the shared IP address for the cluster. However, CARP cannot use the shared IP address because the client requests must be sent to a specific ISA Server. Because of this, CARP does not include the virtual IP address in the script sent to clients or when server-side requests are forwarded to other array members. Instead, CARP uses the specific IP address for the ISA Server computer.
