What version is .h.ka introduced?
I have been playing around with the .h namespace recently and using kdb as a web client. I haven’t figured out how to keep a connection alive using the .h.ka function described in the reference docs here: https://code.kx.com/q/ref/doth/#hka-http-keepalive
I have tried on kdb v3.6 and v4.0, but neither seems to have the function defined. When I hard code the “Connection: keep-alive” into the http response, it is not clear to me that the connection is being reused.
Is this a new feature in 4.1 that hasn’t been specified or an old feature that hasn’t been decommissioned from the documentation? Maybe I am misunderstanding the purpose/use of the .h.ka function entirely, in which case I would appreciate some guidance.
