I have done following things:
img_path = 'abc.jpg'
<img src="{{ img_path | imagine_filter(filter) }}">
So I want to have url with https. Currently I am getting url with http.
I have set router.request_context.scheme: https in parameters. But didn't work.
So actually I want to set vendor/symfony/symfony/src/Symfony/Component/Routing/RequestContext.php
scheme property to https.
