No way to make rewrite rule to work

[EduDifadi]

Hi,

I want to hide an URL by render its content but keeping other URL in browser bar.

I want to use a Rewrite Rule, but there is no way to make it work.

RewriteRule ^lavavajillas-60-cm-black-friday$ /content/30-black-friday-lavavajillas-60-cms [L]

I want to render this page:

https://mydomain.com/content/30-black-friday-lavavajillas-60-cms

but keeping this other URL in the browser bar:

https://mydomain.com/lavavajillas-60-cm-black-friday

No way to make it work. I just get a 404 error or even 500 error. If I use the flag [R] to redirect, it redirects correctly, but I dont achive what I want, as I want to keep the original URL in the bar.

¿Any idea?

Thanks
