## Description

Installation:

You can either install from source (you\’re looking at it), or from the WordPress
[plugin directory](https://wordpress.org/plugins/fastly/).

 1. To proceed with configuration you will need to [sign up for Fastly](https://www.fastly.com/signup)
    and create and activate a new service (unless you already have one). Details of
    how to create and activate a new service can be found [here](https://docs.fastly.com/guides/basic-setup/sign-up-and-create-your-first-service).
    You will also need to find your Service ID and make a note of the string.
 2. You will need to create an API token with the Global API access option selected.
    [Click here for token management screen](https://manage.fastly.com/account/personal/tokens).
 3. Set up the Fastly plugin inside your WordPress admin panel
 4. In your WordPress blog admin panel, Under Fastly->General, enter & save your Fastly
    API token and Service ID
 5. Verify connection by pressing `TEST CONNECTION` button.
 6. In order to get the most value out of Fastly we recommend you upload VCL snippets
    from https://github.com/fastly/WordPress-Plugin/tree/master/vcl_snippets. These
    snippets will add code for following

– Force certain paths to be passed (not cached) e.g. wp-admin, wp-login.php
 – Makes
sure that logged in user sessions are never cached – Handling for serving [stale on error](https://docs.fastly.com/guides/performance-tuning/serving-stale-content.html)

You can upload them by hand or press `Update VCL` button in the UI.

For more information, or if you have any problems, please email us.

_Note: you may have to disable other caching plugins like W3TotalCache or WP Rocket
to avoid getting odd cache behaviour._

 * Pulls in the [Fastly API](http://docs.fastly.com/api)
 * Integrates purging in post/page/taxonomies publishing
 * Includes an admin panel in `wp-admin`
 * Integrates some of the advanced purging options from Fastly API
 * Allows to monitor purging using webhooks for slack

Using this plugin means you won’t have to purge content in Fastly when you make 
changes to your WordPress content. Purges will automatically happen with no need
for manual intervention.

### Customization

#### Edge Modules

Edge Modules are a framework that enables specific functions to be enabled on Fastly
Edge without
 the need to write VCL. Current list of functions that can be included
includes

 * Enable Blackfire metrics and tracing
 * Set CORS headers
 * Enable support for bot detection partners such as Datadome/Netacea
 * Redirect one domain to another e.g. domain.com => www.domain.com
 * Rewrite URLs going to a backend e.g. /sitemap.xml => /media/sitemap.xml
 * Domain masking an external backend/origin

More details can be found at https://github.com/fastly/WordPress-Plugin/blob/master/
EDGE-MODULES.md

#### Image optimization

Image Optimization is a separately contracted feature. Please contact support@fastly.
com to request
 pricing and activation.

Once activated on service level, you will be able to enable it in your blog under
Fastly->Advanced.

Breakdown of IO options:
 Enable Image Optimization in Fastly configuration – Activating
this uploads VCL that steers image traffic to the image optimization service

    ```
    Enable Image Optimization in WordPress - Main switch to activate IO which is needed for all other options to work.

    Enable adaptive pixel ratios - Switch for adaptive pixel ratios implementation. This replaces adaptive pixels srcset to format which Fastly IO can parse and replace. Initially works only on inserted attachments like featured images, but can be applied on content images if enabled.

    Adaptive pixel ratio sizes - Select pixel ratios that will be generated when creating image srcset html.

    Enable image optimization for content images - Safe switch for Image optimization of content images (due to difference from featured images, those are processed differently). To fully utilize, insert full size images in content.
    ```

add_filter(\’purgely_related_keys\’, \’custom_related_keys\’, 10, 2);
 function 
custom_related_keys($keys_array, $post_object) { $keys_array[] = \’custom-key\’;
