Both `absURL` and `relURL` consider the configured value of `baseURL` in your site's [`config` file][configuration]. Given a `baseURL` set to `https://example.com/hugo/`:

```
{{ "mystyle.css" | absURL }} → "https://example.com/hugo/mystyle.css"
{{ "mystyle.css" | relURL }} → "/hugo/mystyle.css"
{{ "http://gohugo.io/" | relURL }} →  "http://gohugo.io/"
{{ "http://gohugo.io/" | absURL }} →  "http://gohugo.io/"
```

The last two examples may look strange but can be very useful. For example, the following shows how to use `absURL` in [JSON-LD structured data for SEO][jsonld] where some of your images for a piece of content may or may not be hosted locally:

{{< code file="layouts/partials/schemaorg-metadata.html" download="schemaorg-metadata.html" >}}
<script type="application/ld+json">
{
    "@context" : "http://schema.org",
    "@type" : "BlogPosting",
    "image" : {{ apply .Params.images "absURL" "." }}
}
</script>
{{< /code >}}

The above uses the [apply function][] and also exposes how the Go template parser JSON-encodes objects inside `<script>` tags. See [the safeJS template function][safejs] for examples of how to tell Hugo not to escape strings inside of such tags.

{{% note "Ending Slash" %}}
`absURL` and `relURL` are smart about missing slashes, but they will *not* add a closing slash to a URL if it is not present.
