Mobile and Web SDK: Does the SDK cache expire?

Question

The Split mobile (iOS and Android) and Javascript browser SDKs download a local cache and store it in a file system. Does the cache have an expire date or TTL?

Answer

The SDK will consider the cache stale if it hasn't been updated for 90 days. In such case it will issue a full download of Split definitions. This is an unlikely scenario since the SDK is continuously synching changes from the Split cloud and updating the cache.
