How to use absolute path in twig functions
I have an application with Symfony2 (2.2). When I want to send a mail, I'm having trouble with the paths, which are all relative paths and obviously aren't working inside emails
for rendering the paths I'm using:
<a href="{{ path('route_name', {'param' : value}) }}">A link</a>
and for assets:
<img src="{{ asset('bundle/myname/img/image.gif') }}" alt="Title"/>
The previous examples work fine but the paths are relative therefore I need to append the domain. I can do something like:
<a href="http://domain.com{{ path('route_name', {'param' => param1}) }}">A link</a>
but this is not the best solution for my problem, as I have different domains.
Update
I found the solution for paths with the url function but I still need a solution for assets.

Symfony 2.7 has a new absolute_url which can be used to generate the absolute url. http://symfony.com/blog/new-in-symfony-2-7-the-new-asset-component#template-function-changes
It will work on those both cases or a path string:
<a href="{{ absolute_url(path('route_name', {'param' : value})) }}">A link</a>
and for assets:
<img src="{{ absolute_url(asset('bundle/myname/img/image.gif')) }}" alt="Title"/>
Or for any string path
<img src="{{ absolute_url('my/absolute/path') }}" alt="Title"/>
on those tree cases you will end up with an absolute URL like
http://www.example.com/my/absolute/path
