Describe the Bug

When passing a valid url like e.g. https://web.archive.org/web/20211125090953/https://github.com/ as href attribute for an next/link element, next/router throws the following warning:

Invalid href passed to next/router: https://web.archive.org/web/20211125090953/https://github.com/, repeated forward-slashes (//) or backslashes \ are not valid in the href

The error message appears inside the executing console and browser console as well.

To Reproduce

Use the following example code snippet and include it in any page:

<Link href={'https://web.archive.org/web/20211125090953/https://github.com/'}>
  Click me
</Link>

@bytrangle, to use Link with valid external http addresses could be for example if you have a link collection, which is partly internal links and external ones and you wanted to avoid the hassle to create your own boilerplate code of:

if internal: <a> Else: <Link>, which is btw. already builtin into the Link component in a similar form

Last time I checked it never was specified anywhere that Link has to be exklusives used for internal linking

External URLs are expected to work with next/link since #15792

It’s rather the logic that checks for external links that should not produce an error in this case.
