A computer-implemented method is provided, including storing, in an authentication server system (10), a URL (44) identifying at least one web page (40), and providing a secure zone browser-side script to be placed on the web page (40). Upon opening of the web page (40) in a browser (22), the secure zone browser-side script triggers execution of a server-side script at the authentication server system (10). The server-side script creates, on the web page (40), an inline frame (116), which is controlled by the authentication server system (10) during a session that is associated with the inline frame (116). The authentication server system (10) retrieves a referrer address from the session, and compares the referrer address with the stored URL (44). Upon finding a match between the referrer address and the stored URL (44), the authentication server system (10) delivers web content to or via the inline frame (116). Other embodiments are also described. |
