ProxyResolver

Create Service

To use this cache resolver, you must first define the cache resolver it will decorate. In this example, we will use the AWS Cache Resolver.

Next, we need to define a service for this cache resolver and inject an array of domains and the cache resolver service to decorate.

# app/config/services.yml

services:
    acme.imagine.cache.resolver.proxy:
        class: Liip\ImagineBundle\Imagine\Cache\Resolver\ProxyResolver
        arguments:
            - "@acme.imagine.cache.resolver.amazon_s3"
            - [ "https://images0.domain.com", "https://images1.domain.com", "https://images2.domain.com" ]
        tags:
            - { name: "liip_imagine.cache.resolver", resolver: "proxy" }

With this configuration, the cache resolver will generate paths such as //images0.domain.com/.../image.jpg, //images1.domain.com/.../image.jpg, and //images2.domain.com/.../image.jpg (instead of the original path returned from the decorated cache resolver, in this example using AWS, //bucket.s3.awsamazoncloud.com/.../image.jpg).

Usage on a Specific Filter

Alternatively, you can set ProxyResolver as the cache resolver for a specific filter set using the following configuration.
