System URL aliases are generated from specific Content item field.
If you go to
Admin -> Content Types and navigate to a Content Type, e.g.
Content > Article, you’ll see labels like “Content name pattern” and “URL alias name pattern”. If “URL alias name pattern” is empty, “Content name pattern” is used. For instance Article has Content name pattern defined as
<short_title|title> which means that if
short_title for a Content item is not present,
title will be used.
So for your case, if “whatever” corresponds to a title/name of a Content item, you can edit that Content item’s Content Type and setup either:
- extra field to be used tor URL alias name pattern
- if “ever” suffix in “whateverever” is constant, you could simply set URL alias name pattern as e.g.
<short_title|title>ever. Of course used field name must correspond to your Content Type field name. The example assumes this is an Article.
Changes in Content type settings will be reflected on next publish operation of a Content item. If you want to apply them globally for all Content items at once, you could use Symfony command
Old URL alias will redirect to a new one.
