Description of the need As Backdrop has redirect functionality, it would be good if the Backdrop would have Internal Redirects. Because doing full redirection is not good behavior of an application and using internal redirects would protect users and will be easy for developers to build on top of it. Here I am specifying, internal redirects for the files to use, not like as URL alias does in the backdrop(they don't create alias for files and all).

Alternatives that have been considered These type of internal redirect can be seen in CMS like Wordpress and all.
