Adobe Commerce Cloud w/ Cloudfare VCL configuration

readme.md

Overview

We (Kraken Commerce) recommend using Cloudflare in front of Adobe Commerce Cloud environments, as Cloudflare provides excellent bot-fighting and performance tools. However a small change is needed in the Magento VCL to pass the user's IP from Cloudflare>Fastly/Varnish>Nginx so that user's IPs are stored in the access logs correct.

Steps:

1. Login to the Magento admin and go to STORES > Configuration > ADVANCED > System and expand the Full Page Cache > Fastly Configuration > Custom VCL Snippets section.
2. Click the "Create" button and add this information:
   1. Name: forward_client_ip (or whatever you want to call it)
   2. Type: recv
   3. Priority: 100
   4. VCL:

if (req.http.CF-Connecting-IP) {
  set req.http.Fastly-Client-IP = req.http.CF-Connecting-IP;
}

3. Click the "Upload VCL to Fastly" button

Testing

1. Before making the change, load url like https://example.com/customer/account/login/?testing=123 in your browser
2. In New Relic, go to Logs and filter by `filePath:"/var/log/platform/*/access.log" message:"testing=123"
3. You'll see the IP listed is not your IP
4. Make the change above
5. The IP listed should now be your IP
