http://symfony.com/doc/current/reference/configuration/framework.html#assets-version-format
Some CDN's do not support cache-busting via query strings, so injecting the version into the actual file path is necessary. Thankfully, assets_version_format is not limited to producing versioned query strings.
The pattern receives the asset's original path and version as its first and second parameters, respectively. Since the asset's path is one parameter, you cannot modify it in-place (e.g. /images/logo-v5.png); however, you can prefix the asset's path using a pattern of version-%%2$s/%%1$s, which would result in the path version-5/images/logo.png.
{# absolute URLs - get the version with asset_version() and append it manually #}
{{ absolute_url(asset('logo.png')) ~ '?' ~ asset_version('logo.png') }}Proposed solution doesn't respect assets_version_format but previous asset('logo.png', version=5) does.
