Creates a preview SecurityToken that can be used to bypass any security on the Flipbook. After creating a token for a specific Flipbook, a specific client IP address and for a given time period, the Flipbook may be accessed using the URL:
<urlToFlipbook>/?SecurityToken=<token> to bypass any security. This is typically used for scenarios where the user is logged in to an intranet and does not want to login to see the Flipbooks, while Flipbooks should be protected from public viewing. Instead of linking directly to the Flipbooks from the intranet, the intranet should link to a local page that creates the securitytoken and then redirects the user to the catalog.
