maxAttempts

The maximum number of attempts to cache fill from this origin. Another attempt is made when a cache fill fails with one of the retryConditions. Once maxAttempts to this origin have failed the failoverOrigin will be used, if one is specified. That failoverOrigin may specify its own maxAttempts, retryConditions and failoverOrigin to control its own cache fill failures. The total number of allowed attempts to cache fill across this and failover origins is limited to four. The total time allowed for cache fill attempts across this and failover origins can be controlled with maxAttemptsTimeout. The last valid, non-retried response from all origins will be returned to the client. If no origin returns a valid response, an HTTP 502 will be returned to the client. Defaults to 1. Must be a value greater than 0 and less than 4.
