Hi John Hoe
For this case. We will look in log and test it. The policy can Hit and caching on the swiftcache but before that no hit because the customer bypass traffic on the F5 Load Balance.
The customer try play video of youku which the policy can Hit but we found the problem we look in log we will see log when the video not able to Hit the video will can play is normally but
the video doing caching from Swiftcache the video will stop load buffer on video.
Please kindly investigate on policy and try testing that able be to play normally.
