Can someone explain the meaning of the X-Backside-Transport header?

Hi yes that is set in the response to the client to indicate some data on what happened to the backend request/response

OK OK means request was sent ok and response was received

OK FAIL means request was sent but response had an error

FAIL FAIL means request could not be sent; or the backend was a loopback

Hi, Is there any way to hide this header in response?

Not for MPGW and WSP:

I've seen this header mentioned a few times, but it's still not very clear for many people. It seems to be used in specific server setups to handle routing or internal traffic. Kind of like how tools such as runt por help you check details behind the scenes, this header also deals with background processes that most users don't usually notice.
