+==== Sending requests during destruction ====
+To ensure that UnityWebRequest operations are completed even if the MonoBehaviour is being destroyed (e.g. when the game is exiting), it appears to be safe on at least some platforms (such as Windows) to manually wait in a loop inside ''OnDestroy'' for ''isDone == true'' on the ''[UnityWebRequest]AsyncOperation'' object returned by ''Send[WebRequest]''.
+  * Note however that mobile platforms don't provide destruction callbacks at all and will usually simply kill the process.
+  * It is recommended to limit the maximum running time of such a loop, and an appropriate time measurement method like ''System.Diagnostics.Stopwatch'' should be used for that since ''Time'' properties will not be updated and ''DateTime.UtcNow'' output can be changed by the user/system.
