### Cache Miss

Under a cache miss the normal request events are seen but an additional event shows the presence of the cache.
Cache Miss will be typical if the item has not been read from the network, is uncacheable, or is past it's
lifetime based on Response cache headers.

 - CallStart
 - **CacheMiss**
 - ProxySelectStart
