Setting Up Secure Referrer Access on Your Tizra Publisher Site 1. If you haven’t already, be sure to contact Tizra to set up the Secure Referrer URL Advanced Site Properties on your Tizra Publisher site. 2. Go to SETTINGS Advanced Site Properties and fill out the following properties: Single sign-on authentication token (Figure 7): This is a random, secret code which is used to generate the Secure Referrer URLs that you use to link to your Tizra-hosted content from other sites. You can enter any string of letters and numbers in this field, though it's good to use something that's hard to guess. Figure 7 Important Note: If you change the Single sign-on authentication token, it will invalidate the existing Secure Referrer URLs and generate new ones. It's useful if for whatever reason security on those URLs has been compromised. Site Linking Match Pattern (Figure 8):This is a Regular Expression you use to indicate the URLs of pages that are acceptable places to link from, when the end-users click on a link that points at your Secure Referrer URLs.
