Ignored referrer
If the user moves from page to page in the browser, you can use javascript to find out under which page the user was before. This URL is called referrer (https://en.wikipedia.org/wiki/HTTP_referer).
You can use this to solve an issue, when you've correctly set a redirect to the homepage in geolizr, but your customers are caught in a loop where they're getting redirected back to the homepage wherever they click on in your store.
The trick with Ignored referrer is that you can enter your own domains there, so there will be no redirect if you come from the said (same or associated) domain. Above all, the feature is interesting for language translations in combination with Langify, as there is often a language domain en.<url>.com which must be changed to another language it.<url>.com in which case you could set en.<url>.com and it.<url>.com as ignored referrer so the redirect doesn't stubbornly send the customers back.
Filter lists (white and blacklist)
With white- and blacklists you can either set exclusive redirects (whitelist) or block redirects (blacklist).
For example, if your contact list can be found under /pages/contacts, you can select blacklist from the filter lists and enter /pages/contacts as URL. This prevents the customers from being redirected. The whitelist behaves exactly inverted. If you set a whitelist to the URL /pages/contacts, it will never redirect except on the page that starts with /pages/contacts.
