Hello there,

I’ve seen several scripts, more or less similar to each others, that override the class PermalinkRewriter \< Generator to rewrite the permalink of a given post/pages. An example [here](https://github.com/mathifold/mathifold_first_version/blob/c80c27533bc863ec3678dde2846c1ac06b7f1e87/_plugins/link.rb).

I’ve been trying to do the same on Jekyll 4.2.2 without success. Even a simple replacement like the one below fails to produce the expected output

```auto
if p.data['slug'].include?("/test/") 
    puts("rewriting the permalink")
    p.data['permalink'] = "/hola"
end

```

The `puts` is generated three times although I’ve only one page with that slug variable. At code level I can see the permalink being replaces, but in fact the page is not accessible via the new permalink but the old one.

Do you have any idea?  
Thanks
