Your network contains a single ISA Server 2006 computer named ISA1. All Internet access for the local network occurs through ISA1.
The network contains a Web server named Server1. Server1 is configured as a SecureNAT client. A Web application runs on Server1 that communicates with an external Web site named www.contoso.com.
You configure ISA1 with two access rules for outbound HTTP access. The rules are named HTTP Access 1 and HTTP Access 2.
HTTP Access 1 is configured to use the All Authenticated Users user set as a condition. HTTP Access 2 is configured to use the All Users user set as a condition, and it restricts outbound HTTP traffic to the IP address of Server1.
You verify that users can access external Web sites. However, you discover that the Web application cannot access www.contoso.com.
You need to allow the Web application to use anonymous credentials when it communicates with www.contoso.com. You also need to require authentication on ISA1 for all users when they access all external Web sites.
What should you do?

A.
On Server1, configure Web Proxy clients to bypass the proxy server for the IP address of the server that hosts www.contoso.com.

B.
On ISA1, add the fully qualified domain name (FQDN) www.contoso.com to the list of domain names available on the Internal network.

C.
On ISA1, disable the Web Proxy filter for the HTTP protocol.

D.
Modify the order of the access rules so that HTTP Access 2 is processed before HTTP Access 1.
