This method is really just a stub. A few things that need to be completed:

- The cookie name should be configurable. See https://github.com/misterbisson/bstat/pull/8#discussion_r12565707
- [The actual cookie is saved as JSON](https://github.com/misterbisson/bstat/pull/8/files#diff-cf0991899b9a89a6f955844bf105fcd0R345), so a single variation can't be read like that before parsing the JSON.
  - Once the JSON is parsed, it should probably be saved in a class var, so subsequent requests can read the data without re-parsing.
