SYMPTOMS
Consider the following scenario:
 * You publish a Web site in Microsoft Internet Security and Acceleration (ISA) Server 2006.
 * In the Web listener, ISA Server is configured to use forms-based authentication to authenticate client requests.
 * ISA Server is configured to present an RSA SecurID form to the client users.
 * The RSA SecurID logon form is customized for mobile devices by using XHTML-Mobile Profile (XHTML-MP) and cHTML.

However, the RSA SecurID logon form may not work. After a user submits the customized logon form from a mobile device, the Web browser does not open the desired Web site.



CAUSE
If you use forms-based authentication and the RSA SecurID authentication scheme to publish a Web site, the user receives a logon form after the user logs on successfully. This logon form redirects the Web browser to the original URL that the user accesses. ISA Server uses a Refresh header to implement the redirection. However, some devices may not understand this header.
