* `{{ "mystyle.css" | absURL }}` → "http://mysite.com/hugo/mystyle.css"
* `{{ "mystyle.css" | relURL }}` → "/hugo/mystyle.css"
* `{{ "http://gohugo.io/" | relURL }}` → "http://gohugo.io/"
* `{{ "http://gohugo.io/" | absURL }}` → "http://gohugo.io/"
**Note:** If `canonifyUrls` is enabled, the last example above will be "/mystyle.css". These functions are smart about missing slashes, but will not add one to the end if not present.
The last two examples may look funky, but is useful if you, say, have a list of images, some of them hosted externally, some locally:
```
<script type="application/ld+json">
{
"@context" : "http://schema.org",
"@type" : "BlogPosting",
"image" : {{ apply .Params.images "absURL" "." }}
}
</script>
```
The above also exploits the fact that the Go template parser JSON-encodes objects inside `script` tags.
