How Fastly works
Show full descriptionShow less
Installation:
You can either install from source (you\’re looking at it), or from the WordPress plugin directory.
To proceed with configuration you will need to sign up for Fastly 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. You will also need to find your Service ID and make a note of the string.
You will need to create an API token with the Global API access option selected. Click here for token management screen.
Set up the Fastly plugin inside your WordPress admin panel
In your WordPress blog admin panel, Under Fastly->General, enter & save your Fastly API token and Service ID
Verify connection by pressing TEST CONNECTION button.
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
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.

Customization

Redirect one domain to another e.g. domain.com => www.domain.com

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.
