How to get the raw headers

[ciokan]

I need to get the raw headers (or the headers in the order they were sent - important) of the request. A map won't hold that unfortunately so I'm curious if it is possible with echo. Something similar with fiber's c.Request().Header.RawHeaders(). Any ideas?

Echo relies on Go standard library http.Server to request parsing and to know the raw request bytes you probably need some kind of low level net.Conn magic on the listener side.

Is it for debugging proposes or some "business" use-case?

It's a business use case unfortunately. Thanks for the help.
