    HTTP_REQUEST is in the request which goes to the backend server, HTTP_RESPONSE is for the response from the server to the client. To correct your iRule:

    when HTTP_REQUEST {
  if { [HTTP::header Authorization] contains "Basic" } {
    log local0.debug "Basic: [HTTP::header Authorization]"
    HTTP::insert X-HUB-BASIC "[HTTP::header Authorization]"
  } elseif { [HTTP::header Authorization] contains "Bearer" } {
    log local0.debug "Bearer: [HTTP::header Authorization]"
    HTTP::insert X-HUB-Bearer "[HTTP::header Authorization]"
  }
}

Hi! Thanks for the reply!
That insert wouldn't be inside the HTTP_REQUEST, would it?

    yes, it would. Presumably you want to insert the HTTP header into the request which goes to the backend server.

      Yes, I want to insert the header inside the request which goes to the backend server. Actually I don't know if it would be in HTTP_RESPONSE or HTTP_RESPONSE_RELEASE.

      Would it be something like this?
      when HTTP_RESPONSE {
      if { [HTTP::header Authorization] contains "Basic" } {
      log local0.debug "Basic: [HTTP::header Authorization]"
      HTTP::insert X-HUB-BASIC "[HTTP::header Authorization]"
      } elseif { [HTTP::header Authorization] contains "Bearer" } {
      log local0.debug "Bearer: [HTTP::header Authorization]"
      HTTP::insert X-HUB-Bearer "[HTTP::header Authorization]"
      }
      }
