The [contents of HTTP request log files](https://docs.wpvip.com/logs/log-shipping/log-contents/)
that are shipped by the [HTTP request Log Shipping](https://docs.wpvip.com/logs/log-shipping/)
feature will now include a `cache_segment` field. For applications leveraging the
[VIP Cache Personalization API](https://docs.wpvip.com/caching/page-cache/the-vip-cache-personalization-api/)
the value of the `cache_segment` field is populated by the value of the `vip-go-
seg` cookie and will otherwise be blank.
