| Q. | What type of authentication should I use for my published Web sites? Should I force users to authenticate at the Incoming Web Requests listener and internal network Web server? | |
| A. | You can use any type of authentication you like with an internal network Web site that you're publishing with Web publishing rules. It's important that you only require authentication at one location. You should not require authentication at the Incoming Web Requests listener and the internal Web site. ISA Server will not support this type of double authentication. The only time you can authenticate at the Incoming Web Requests listener and the internal network Web server is when you authenticate with the Incoming Web Requests listener using a client certificate. If you authenticate with the Incoming Web Requests listener using a client certificate, then you can use another form of authentication to authenticate with the internal network Web server. In general, we prefer authenticating with the Incoming Web Requests listener, as this offloads the authentication processing off the internal network server and places it on the ISA server. | |
