What is cf-railgun header represents?


I have activated Railgun.

I see this header cf-railgun varies with values.

Like cf-railgun: bbaac487d5 stream 0.000000 0200 3350

I wish to know what are these values stands for.

And still, sometime, I will see cf-railgun: direct (starting new WAN connection) instead of cf-cache-status: DYNAMIC or cf-cache-status: REVALIDATED.

I guess that cf-cache-status: DYNAMIC is the best. This is a test domain and thus no much traffic.

Is this usual or do I need to make any changes anywhere to get the maximum benefit of Railgun?
