Twig Filter

The |app filter returns an address relative to the public path of the website. The result is an absolute URL, including the domain name and protocol, to the location specified in the filter parameter. The filter can be applied to any path.

<link rel="icon" href="{{ '/favicon.ico'|app }}" />

If the website address is https://octobercms.com the above example would output the following:

<link rel="icon" href="https://octobercms.com/favicon.ico" />

It can also be used for static URLs:

<a href="{{ '/about-us'|app }}">
    About Us

The above would output:

<a href="https://octobercms.com/about-us">
    About us

Note: The |page filter is recommended for linking to other pages.
