Has link with a URL referencing LocalHost or

This means that the URL in question contains at least one outgoing anchor link with a URL referencing LocalHost or

Why is this important?

LocalHost is the standard host name given to the address of the local computer, and the IP address for your localhost is The local server isn't connected to the internet, but makes it possible to see your site in the browser as if you're viewing it online - so LocalHost addresses may be used during development of a website.

Since these files are not publicly accessible, when the website is set live, the hostname is replaced with the actual domain name.

This Hint addresses instances where links remain to LocalHost addresses, which will be inaccessible to the public and should be removed/corrected.

What does the Hint check?

This Hint will trigger for any internal URL which contains at least one outgoing anchor link where the href references LocalHost or

Examples that trigger this Hint:

Any of the example links below would trigger the Hint.

An anchor with a URL referencing with port

<a href="">Test</a>

An anchor with a URL referencing without port

<a href="">Test</a>

An anchor with a URL referencing LocalHost with port

<a href="http://localhost:1234/test">Test</a>

An anchor with a URL referencing LocalHost without port

<a href="http://localhost/test">Test</a>

How do you resolve this issue?

Identify the anchors which reference LocalHost or in the href attribute, and correct each one on a case-by-case basis - which may require reviewing the code that generates the links.

Our recommendation is to remove all references to such files, and replace the links with publicly available resources. If no replacement page is publicly available, then remove the link entirely.
