Cache Resolver (deprecated)
Edit this pageCache Resolver (deprecated)
Warning
This cache resolver is based on the discontinued Doctrine Cache library.
It is recommended to use the PsrCacheResolver instead.
The CacheResolver cannot be used by itself. Instead, it is a "wrapper" for
another resolver.
Dependencies
This cache resolver requires the Doctrine Cache library, which can be installed by executing the following command in your project directory:
1
$ composer require doctrine/cacheConfiguration
First, you need to setup the required services. In this example we're wrapping an
instance of AmazonS3Resolver inside this resolver.

acme.imagine.cache.resolver.amazon_s3.cache:
class: Liip\ImagineBundle\Imagine\Cache\Resolver\CacheResolver
arguments:
- "@cache.memcache"
- "@acme.imagine.cache.resolver.amazon_s3"
- { prefix: "amazon_s3" }
tags:
- { name: "liip_imagine.cache.resolver", resolver: "cached_amazon_s3" }There are three options available:
global_prefix: A prefix for all keys within the cache. This is useful to avoid colliding keys when using the same cache for different systems.prefix: A "local" prefix for this wrapper. This is useful when re-using the same resolver for multiple filters. This mainly affects the clear method.index_key: The name of the index key being used to save a list of created cache keys regarding one image and filter pairing.
Usage
After configuring CacheResolver, you can set it as the default cache resolver
for LiipImagineBundle using the following configuration.
1 2 3 4
# app/config/config.yml
liip_imagine:
cache: cached_amazon_s3Usage on a Specific Filter
Alternatively, you can set CacheResolver as the cache resolver for a specific
filter set using the following configuration.
1 2 3 4 5 6 7 8 9
# app/config/config.yml
liip_imagine:
filter_sets:
cache: ~
my_thumb:
cache: cached_amazon_s3
