Added a new option in the LUNA Administrator to turn off facets in a Credential, hiding entry points in the LUNA Viewer to the Browse by Category pages, Browse by Title pages and Facet Browsing (Who, What When Where) in an effort to stop aggressive crawlers making LUNA useless for clients and causing downtime. The feature works with the Anonymous credential to hide facets that are part of public collections, while allowing them to remain visible to users accessing LUNA on campus or with a user account.
Implemented a reCaptcha option, as an alternative to turning off facets, to verify a user is not a robot when accessing the 4W Facets and the Browse by Category page. ReCaptcha is session based and will only display once during a user's session. This method is recommended if you have public collections and want to keep the Who, What, Where, When facets visible in the LUNA Viewer.
