What is the benefit of these functions?
It seems they are only called from tests but not from the plugin code itself.

They are called just under by getOutgoingRequestAttributesOnResponse and getIncomingRequestAttributes

At least for outgoing HTTP users may specify headers with any casing.

They should be lower-cased by node when set: https://github.com/nodejs/node/blob/master/lib/_http_outgoing.js#L572

You refer to the object used by node http internally on symbol kOutHeaders accessible via the apis setHeader/ getHeader/... on outgoing requests.
But actually this is not applicable here. outgoing messages have not .header property at all.
But it seems this is no problem because this plugin captures content-size only for server requests (incoming) and client response (also incoming) where node parses and prepares the lowercased headers.

@vmarchaud do @Flarna's fixes need to be applied to the plugin version too? |
No the original PR for the http plugin have the correct version, i'm not sure why my cherry-pick resulted in this. Even more surprised than neither typescript or tests had issues with this. |
