AP-5131 Access Point Product Reference Guide
5-44
When a client requests a URL from a Web server, the login handler returns an HTTP redirection status
code (for example, 301 Moved Permanently), which indicates to the browser it should look for the
page at another URL. This other URL can be a local or remote login page (based on the hotspot
configuration). The login page URL is specified in the location’s HTTP header.
To host a Login page on the external Web server, the IP address of the Web server should be in the
White list (list of IP addresses allowed to access the server) configuration. Ensure the Login page is
designed so the submit action always posts the login data on the AP-5131.
To define the White List for a target WLAN:
1. Click the White List Entries button from within the WLAN’s Hotspot Config screen.
2. Click the Add button to define an IP address for an allowed destination IP address.
3. Select a White List entry and click the Del button to remove the address from the White List.
4. Click OK to return to the Hotspot Config screen where the configuration can be saved by
clicking the Apply button.
Now user enters his/her credentials on Login page and submits the page to AP5131. Login
Handler will execute a CGI script, which will use this data as input.
5. Click Cancel to return to the Hotspot Config screen without saving any of the White List
entries defined within the White List Entries screen.
