The Forefront TMG Web proxy supports requests from any browser that conforms to standards of the Conseil Europeen pour la Recherche Nucleaire (CERN). The Forefront TMG Web proxy allows Web access to nearly every desktop operating system, including Windows Vista, Windows Server 2008, Windows XP, Windows NT, Windows 2000, Windows 98, Windows 95, Macintosh, and UNIX operating systems.
The Forefront TMG Web proxy works at the application level on behalf of a client requesting an Internet object retrievable through one of the protocols supported by the filter: HTTP, HTTPS, and FTP (download requests). The Web proxy protects all Web browser access. The Web proxy operates with a Web proxy client, which can be any client computer that uses a CERN-compliant application that is configured to use the Forefront TMG Web proxy.
A server running Internet Information Services (IIS) can be installed on a Forefront TMG computer, but this is not required. For more information about IIS and Forefront TMG, see Internet Information Services Separation.
You can use the secure Web publishing feature of Forefront TMG in conjunction with Internet Information Services (IIS) or other Web servers to publish to the Internet without compromising the security of your internal network. Forefront TMG uses Secure Web publishing and reverse hosting to send requests to Web-publishing servers connected behind the Forefront TMG Web proxy computer. The Forefront TMG Web proxy supports the use of Secure Sockets Layer (SSL), and also supports Web (ISAPI) filters.
The Forefront TMG Web proxy includes the Forefront TMG cache, described in About the Forefront TMG Cache.
