If we have a link (reference), is there any particular reason, why using it’s (link’s) alias (cool urls via aliases) rather than the actual target URL?
For example, one might want to create menu, some main one or some additional. But the documents are somewhere deep in the structure, so it’s good reason to create a folder "Some menu" and put links to the documents into this folder. But at the menu, i want links to the documents, not to the links (that would redirect browser to the documents).
