I am attempting to use volt tag helpers such as stylesheet_link to link to an external URL without protocol prefix.
Example usage without protocol proves to be problem free:
{{ stylesheet_link('http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css') }}
Generates
<link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" />
.
However, whenever the protocol prefix is obmitted (ie/ //netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css):
{{ stylesheet_link('//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css') }}
Generates incorrect URL:
<link rel="stylesheet" type="text/css" href="[SITE_PREFIX]//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" />
Is it due to my incorrect usage? or is this an existing bug with volt?
Try specifying that it's not local, see the docs.
{{ stylesheet_link('//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css', false) }}
