This code change looks good. We will also want to update the page_rule resource documentation that is shown on the website (it is found at https://github.com/terraform-providers/terraform-provider-cloudflare/blob/master/website/docs/r/page_rule.html.markdown). Once that's added, we can 🚢 this.

Sure @jacobbednarz. One more qq, this is a blocker for the feature that I am working with my current project at my company. We are using Terraform v0.11.13 Enterprise version. How do I make this change go in our usage?

[jacobbednarz]

v0.11.13 is the terraform version whereas this will update the provider which is currently v1.16.1 (terraform is "core" whereas "providers" are plugins for the core). Once this is merged, it will be a part of the next release and you can update to it by re-running terraform init.

If you can't wait for us to cut a release, you can pull the code locally and run it yourself. Instructions can be found at https://github.com/terraform-providers/terraform-provider-cloudflare#building-the-provider.
