Portal Authentication Protocol
During Portal authentication, HTTP/HTTPS and Portal protocols are used.
The client first sends a connection request and an authentication request carrying the user name and password in sequence to the Portal server through HTTP or HTTPS. Upon receipt of the authentication request, the Portal server starts authentication
in either of the following ways:
- The Portal server sends a Portal authentication request carrying the user name and password to an access device through the Portal protocol. The Portal protocol is compatible with the Portal 2.0 protocol of China Mobile Communications Corporation (CMCC), and supports basic functions of the Portal 2.0 protocol. For details, see Portal Authentication Process Based on the Portal Protocol.
- The Portal server instructs the client to initiate a Portal authentication request to the access device through the HTTP or HTTPS protocol. The client then initiates a Portal authentication request carrying the user name and password to the access device through the HTTP or HTTPS protocol. For details, see HTTP- or HTTPS-based Portal Authentication Process.
It is recommended that an access device use the Portal protocol to communicate with the Portal server. If the Portal server does not support the Portal protocol, the access device can use the HTTP or HTTPS protocol.
If a built-in Portal server is used for Portal authentication, the access device supports only the Portal protocol.
The HTTP or HTTPS protocol can be used as the Portal access protocol or Portal authentication protocol. This section describes the Portal authentication protocols supported by access devices.
