Note:

The Web listener can also be configured for HTTP authentication or for forms-based authentication. However, client authentication will then be performed over HTTP without encryption. Because user credentials will be transmitted in plain text, such configurations are considered insecure and are disabled by default. To enable such a configuration, open the properties of the Web listener. On the Authentication tab, click Advanced, and then select the Allow client authentication over HTTP check box. For best security practices, use such a configuration only if you have an SSL accelerator in front of the Forefront TMG computer. Forefront TMG treats a farm of servers behind a load-balancing device as a single server. Although this option is supported for publishing a load-balanced farm, we recommend that you use the integrated load-balancing support that is provided by a server farm created in Forefront TMG rather than a load-balancing device. Forefront TMG publishing for server farms provides improved client affinity, which can be configured to operate by using a cookie, rather than depending on the client IP address. This is a distinct advantage in a situation where a device between the load-balancing device and Forefront TMG, such as a NAT device, hides the client IP address. Web publishing rules match incoming client requests to the appropriate Web site on the Web server.  You can create Web publishing rules that deny traffic, to block incoming traffic that matches the rule conditions. Forefront TMG does not treat paths as case-sensitive. For example, if your Web server includes both foldera and folderA, and you publish a path to one of the folders, both folders will be published.
