Configure URI accessibility for Gapwalk applications
This topic describes how to configure the filtering of URIs for Gapwalk applications. This feature does not require an identity provider (IdP).
To block a list of URIs, add the following two lines to the
application-main.yml of your modernized application, replacing
URI-1, URI-2, and so on, with the URIs that
you want to block.
gapwalk-application.security.filterURIs: enabled gapwalk-application.security.blockedURIs:URI-1,URI-2,URI-3
