Current behaviour

The configuration example of the content cache policy does not work. This is the configuration suggested in the doc:

{
  "name": "apicast.policy.content_caching",
  "version": "builtin",
  "configuration": {
    "rules": [
      {
        "cache": true,
        "header": "X-Cache-Status-POLICY",
        "condition": {
          "combine_op": "and",
          "operations": [
            {
              "left": "{{method}}",
              "left_type": "liquid",
              "op": "==",
              "right": "GET"
            }
          ]
        }
      }
    ]
  }
}

this pattern:

 {{method}} 

is not working. When used, the content cache is not taking any effect and hence no x-cache-control-status is being returned.

In order to make work that example the pattern to be used is:

{{request_method}}

Expected behaviour

Replace method with request_method in the configuration sample given.
