Symfony 4 bundle for creating/validating cacheable responses
============================================================

[](#symfony-4-bundle-for-creatingvalidating-cacheable-responses)

Introduction
------------

[](#introduction)

Easily make cacheable `Response` objects to be returned from your controllers for content that:

- can change
- doesn't always change on every single request
- can be cached for an unknown amount of time

A created cacheable response has the following headers set:

- `Cache-Control: must-revalidate, public`
- `Last-Modified: `
- `Etag: `

Subsequent requests made by a browser will include a `If-None-Match: ` header which we can then use to determine if we should tell the browser to re-use the previously-cached response.

Installation
------------

[](#installation)

### Install via composer:

[](#install-via-composer)

Use composer to add as a project dependency:

```
composer require simplytestable-pagecache-bundle:^0.1

```

### Update your database schema:

[](#update-your-database-schema)

Details of cache-related headers previously sent are persisted to an object store. This bundle provides an entity, you need to update your database schema to allowt the entities to be persisted.

```
./bin/console doctrine:migrations:diff
./bin/console doctrine:migrations:migrate
