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
