The URL Mappings rule defines simple URL patterns that you can use in your application for your work items (cases), reports, landing pages, and so on.
You can represent your work items with simple, short URLs so that you can more easily share your work items with other users of the same Pega Platform application. Simple, meaningful and readable URLs make it easier for users to collaborate.
You can also specify which patterns to use to generate canonical URLs for your case types. Canonical URLs improve search engine optimization because they prevent duplicate content issues by indicating the preferred (standard) URL version. By generating canonical URLs for a case type, you make all instances of this case type searchable by third-party search engines.
