Portal Server supports the following browsers as clients:

• Netscape™ Communicator 4.7x or higher
See the Portal Server 6 Release Notes for updates to this list.
Multiple client types, whether based on HTML, WML, or other protocols, can
access Access Manager and hence Portal Server. For this functionality to work,
Access Manager uses the Client Detection service (client detection API) to detect
the client type that is accessing the portal. The client type is then used to select the
portal template and JSP files and the character encoding that is used for output.

capabilities of the Portal Server platform to mobile devices and provides a
framework for voice access. The software enables portal site users to obtain the
same content that they access using HTML browsers.
Mobile Access software supports mobile markup languages, including xHTML,
cHTML, HDML, HTML, and WML. It can support any mobile device that is
connected to a wireless network through a LAN or WAN using either the HTTP or
HTTPS protocol. In fact, the Portal Server Mobile Access software could support
any number of devices, including automobiles, set-top boxes, PDAs, cellular
phones, and voice.
NOTE Currently, Access Manager defines client data only for supported
HTML client browsers, including Internet Explorer and Netscape
Communicator. See the Access Manager documentation for more
information.
