# Terraform example

The following example defines a single Cache Response Rule for a zone using Terraform. The rule strips Set-Cookie and ETag headers from JavaScript file responses before caching.

Terraform `cloudflare_ruleset` resource

```
# Cache Response Rule to strip headers from JS responsesresource "cloudflare_ruleset" "cache_response_rules_example" {  zone_id     = "<ZONE_ID>"  name        = "Cache Response Rules"  description = "Configure cache settings for origin responses"  kind        = "zone"  phase       = "http_response_cache_settings"
  rules {    ref         = "strip_js_headers"    description = "Strip caching headers from JS file responses"    expression  = "http.request.uri.path.extension eq \"js\""    action      = "set_cache_settings"    action_parameters {      strip_etags      = true      strip_set_cookie = true    }  }
  rules {    ref         = "tag_api_responses"    description = "Tag API responses for targeted purging"    expression  = "starts_with(http.request.uri.path, \"/api/\")"    action      = "set_cache_tags"    action_parameters {      operation = "set"      values    = ["api-response", "dynamic-content"]    }  }
  rules {    ref         = "cache_control_200"    description = "Set cache-control for successful responses"    expression  = "http.response.code eq 200"    action      = "set_cache_control"    action_parameters {      s_maxage {        operation      = "set"        value          = 86400        cloudflare_only = true      }      must_revalidate {        operation = "set"      }    }  }}
```

Use the `ref` field to get stable rule IDs across updates when using Terraform. Adding this field prevents Terraform from recreating the rule on changes. For more information, refer to [Troubleshooting](https://developers.cloudflare.com/terraform/troubleshooting/rule-id-changes/#how-to-keep-the-same-rule-id-between-modifications) in the Terraform documentation.

For additional guidance on using Terraform with Cloudflare, refer to [Terraform](https://developers.cloudflare.com/terraform/).
