Can't redirect URL with dot

Hello, I am currently testing the URL Redirect Plugin and have discovered an issue. When attempting to 301 redirect a URL that contains a "." the redirect does not work.

For example the URL: /20046/0/Marine-Power-881301-New-3.0L-GM-Marine-Long-Block
I get a 404 error rather than a redirect when I try this. Is there a solution?

Thanks.

Do you use nop 3.90 (3.80)?
If yes.
You can't redirect such URLs (you need to change IIS handler).
Because IIS sees such URLs ad link to file on disk.
Nop 4.0 (4.10) use ASP.NET Core.
This new technology allows to redirect such URLs.
