pixelcodenl / cache-header-control

Craft plugin for controlling the HTTP Cache-Control and Expiration headers from your templates.

Craft HTTP cache header control plugin

This plugin makes it easier to set up an Cache-Control and Expiration HTTP header from your templates.

Installation

Install it with Composer:

composer require pixelcode/cacheheadercontrol

Usage

Use it in your template(s):

{% http_cache %}

This will set the headers based on the plugin configuration.

{% http_cache false %}

This will disable cache for the template.

{% http_cache '+5 minutes' %}

This will set the cache expiration to 5 minutes after the current time, so the template will be cached for 5 minutes.

You can use all 'strtotime' formats here, see http://php.net/manual/en/function.strtotime.php.

Configuration

Options

enableCache

Default: true

Enable or disable cache headers. If this is set to 'false' and you add the 'http_cache' tag to a template, the Expiration header will get the value of {time} - 1 second.

defaultCacheExpiration

Default: +15 minutes

Default expiration used when you use '{% http_cache %}' without any custom options.

Overwrite configuration

You can overwrite the configuration by creating a PHP file with the name 'cacheHeaderControl.php' in the 'craft/config' folder.

Example for overwriting the default expiration:

<?php

return [
    'defaultCacheExpiration' => '+5 minutes',
];
