To specify a URL for the web page that displays when this WebVPN user logs in, enter the homepage command in username webvpn configuration mode. To remove a configured home page, including a null value created by issuing the homepage none command, enter the no form of this command. The no option allows inheritance of a value from the group policy. To prevent inheriting a home page, enter the homepage none command.
The none keyword indicates that there is no WebVPN home page. It sets a null value, thereby disallowing a home page and prevents inheriting a home page.
The url-string variable following the keyword value provides a URL for the home page. The string must begin with either http:// or https://.
There is no default home page.
