It's not clear to me from the docs how to do this (other than a custom function for transformUrl). I was very surprised this isn't the default, as that is the default for the grunt version of this plugin (I'm in the process of migrating some code from grunt to gulp).
Specifically, I would've expected something like:
$templateCache.put('template/foo.html', 'content')
but instead I'm getting
$templateCache.put('/template/foo.html', 'content')
