Proxy Array Parameters that Are Replicated When Automatic Synchronization Is Enabled (260011)

MORE INFORMATION

When proxy array replication occurs, the array member you are currently administering is always updated first. When you enable automatic synchronization for a proxy array, the following parameters are replicated in the entire array:

• Domain filters.
• Web Proxy service protocol access control information.
• Web Proxy service caching options, including advanced caching options such as cache filters.
• Web Proxy service upstream routing options.
• Web Proxy service publishing (reverse proxying) information.
• WinSock Proxy service protocol definitions.
• WinSock Proxy service access control information.
• Socks Proxy service permissions.
• Logging configuration for each service, including packet filter logging.
• Packet filter alerting information.
• Local address table (LAT) information.
• Client configuration information.

The following parameters are not replicated in the proxy array:

• Web Proxy service enable caching flag.
• Web Proxy cache size.
• Web Proxy cache disk location.
• Web Proxy service directory information.
• Logging folders for each service.
• Packet filters.
• Microsoft Internet Information Services (IIS) WWW service password authentication settings.

NOTE: If you receive an error message stating that the IIS authentication settings do not match, you can change the settings in the WWW service by using Internet Service Manager (ISM).

Also note that the anonymous IUSR_computername account is not correctly replicated across a proxy array. You should grant user permissions to the Everyone account instead of the IUSR_computername account in the Web Proxy service if the following conditions apply:

• You have multiple proxy server computers configured in an array.
• You want to permit anonymous access to Web publishing from the local IIS computer.
• You want to authenticate users for client requests that pass through the Web Proxy service. Therefore, if you have enabled Access Control for the Web Proxy service, then you must add the Everyone group to the access list.
