# ProxyResolver

The ProxyResolver is a `decorator` for every other Resolver

This Resolver adds the possibility to use Proxy Hosts for your Assets.
If no Proxy Domains are set, it behaves like the  underlying `Resolver`

## Set Proxy Domains

In order to use this Resolver you must create a Service and inject some domains and your underlying Resolver

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

Now your Resolver would generate following Urls `http://images0.domain.com/thumbs/article_thumb/foo.jpg` instead of the original path from the underlying Resolver `bucket.s3.awsamazoncloud.com/thumbs/article_thumb/foo.jpg` for every relevant Action.
