What is it ?

This bundle provides a simple page caching solution working as an in-app reverse proxy.

Requirements

"php": "^5.3.9|^7.0",
"symfony/cache": "^3.1"

Installation

Download the bundle

Download composer at https://getcomposer.org/download/

composer require bigyouth/page-cache-bundle

Register the bundle

Enable the bundle by adding it to the bundles array of the registerBundles method in your project's app/AppKernel.php file :

<?php

# app/AppKernel.php

// ...

class AppKernel extends Kernel
{
        public function registerBundles()
        {
            $bundles = [
                // ...

                new Bigyouth\BigyouthPageCacheBundle\BigyouthPageCacheBundle(),
            ];

            // ...
        }

        // ...
}

Configuration

Here is the default bundle configuration :

# app/config/config.yml


bigyouth_page_cache:
    enabled: false
    ttl: 300
    type: "filesystem"
    exclude: []

enabled

default : false

Set to true to enable the bundle.

ttl

default : 300

Cache lifetime. This value varies by +5%/-5% to avoid multiple caches to expire at the same time.

type

default: filesystem

Two value can be set for this parameter : filesystem and redis.

If you use filesystem, the cache will be written in the cache folder : var/cache/by_cache.

exclude

default : empty array

This parameter allows you to define url schemes that will be excluded from the page caching.

ex :

exclude:
    - "app_dev.php"
    - "back"
    - "login"
    - "logout"
    - "login_check"

Every url that contains one of the terms above will not be processed by the BigyouthPageCacheBundle.

redis_host

default : localhost

Redis host. This parameter is only used when the type parameter is set to redis.

redis_port

default : 6379

Redis port. This parameter is only used when the type parameter is set to redis.

Usage

Caching

To use the BigyouthPageCacheBundle, your controller must extend the PageCacheController.php class and use the render function :

<?php

// ...

class AcmeController extends PageCacheController
{

        // ...
        public function indexAction(Request $request)
        {

            // ...

            return $this->render('FrontBundle:Page:index.html.twig');

        }
}

The PageCacheController rewrites the render function to manage and render cache data. All of your controller actions that use the render function will be cached.

Cache invalidation

The BigyouthPageCacheBundle uses cache tags to identify your cache data. The tags are defined by the url scheme of the cached page.

For example, the page behind /products/list/my-product will be tagged with products, list and my-product.

Therefore you can invalidate a product page by doing the following in your controller :

// ...

$this->get('by.page_cache')->invalidate(["my-product"]);

// ...

or if you want to invalidate all product pages :

// ...

$this->get('by.page_cache')->invalidate(["products"]);

// ...
