Putting data into cache

This API request places the object into Backendless cache and maps it to the specified key. If the timeToLive argument is not set, the object will expire from cache in 2 hours from the time when it is put in cache.

Method:

PUT

<key> Key assigned to the object to identify it in cache. The key is used to retrieve the object from cache or to check if the cache still contains the object.
