We need to support authenticated webpages driven by Blocks. For this to happen we need to be able to check if the user is authenticated, redirect to the SSO page and then get back to the original webpage. Currently the SSO integration is with the EntryScape start page being the redirectURL.

It would be sensible to allow a range of different webpages to be whitelisted, e.g. all landingpages for datasets in a catalog or a certain search filter as a parameter.

Hence, it would be good if the whitelist was based on a regular expression or any redirectURL on a given domain.
