Is it posible to have a

<base href='myPageBase/' /> 

generated in the index.volt by using the default config? I would like to only set the base-tag once.

UPDATE solved it

I created a BaseController

<?php

use Phalcon\Mvc\Controller,
    Phalcon\Tag;

class ControllerBase extends Controller
{
    public function onConstruct(){
        $this->view->baseTag = Tag::tagHtml("base",array("href" => $this->url->getBaseUri()));
    }
}

and used it in volt like this:

...
<head>
{{ baseTag }}
</head>
...

UPDATE 2 - even easier

<base href="{{ url.getBaseUri() }}"/>
