Forefront Unified Access Gateway (UAG) uses an ASP-based Web application, called InternalSite, to provide authentication services for portal trunks, to install client endpoint components, and to automatically detect the user language. When end users log in to Forefront UAG, a login page is provided by InternalSite, in which the user can select the language to be used by the portal. When using Forefront UAG, you can customize text strings for each language, and for each trunk that is published through Forefront UAG.
 Note: |

| Changes made to the InternalSite also apply to the System Information window in the portal. |
Forefront UAG supports several types of endpoint devices. The different versions of the InternalSite Web application correspond to the following groups of endpoint devices:
- Computer—Home or office computers
running Windows, Macintosh, or Linux operating systems.
- Premium mobile—Mobile devices running
Windows Mobile or the Apple iPhone.
- Non-premium mobile—Mobile devices
other than devices running Windows Mobile or the Apple iPhone.
| Note: |

| An additional version of the InternalSite Web application provides an Outlook Web Access (OWA) look and feel for the end user. |
Using the CustomUpdate mechanism (described in About the CustomUpdate mechanism), you can customize:
- Visual and standard text
attributes—Modifications affect all of the relevant parameters
in the pages. You cannot assign different parameters to each page
in the group. For example, if you change the logo graphic and text,
the change is applied uniformly on all pages.
- Style sheets that affect styles such as
fonts and colors—Modifying style sheets requires a working
knowledge of cascading style sheets.
The default items and values for the elements that make up the InternalSite are located under the ...\Microsoft Forefront Unified Access Gateway\von\InternalSite directory.
