How to replace part of URL with another value (mod_rewrite) or proxy?

Question

Apache HTTP Server

When using substitute to replace words on the page, some of the links were replaced. As a result, the pages are not found.
It was test.ru/Asdf-content/AB1234
It became test.ru/Ghjk-content/CD1234
The content of the pages remained unchanged, except for the replacement of some words and links.
How to display the old address at the new address via mod_rewrite or mod_proxy?

Answer 1

IMHO the capabilities of mod_alias and its Alias ​​or Redirect directives will suffice here .
Examples of directives are on the links.
