A recent update in Chromium based browsers (such as Chrome and Edge) and Firefox has resulted in a new default referrer policy being applied which may impact referring URL access to Emerald Insight. 


For referring URL access to function correctly, we require a referrer policy in place that passes the full URL information to Emerald. Unfortunately, the new default policy in these updates (‘strict-origin-when-cross-origin’) does not do this, restricting the information we receive for authentication.


The suggested referrer policy to maintain access is the previous default ‘no-referrer-when-downgrade’. This enables referring URL information to be passed in full to secure sites only. 


The easiest way to add this referrer policy, without affecting further links or your wider site, is direct to the link to Emerald within the HTML. This can be seen in example below

 

 

The suggested code placed after the link seen here is referrerpolicy=”no-referrer-when-downgrade”


Further information can be found in the Google update regarding the options for the setting of referrer policies on for your site including:


Different policies can be set for different pages so you will not be required to make the change site-wide and only on the page referring URL access links are hosted. 


Should you require any further information regarding referrer-policies this can be found https://www.w3.org/TR/referrer-policy/#referrer-policies
