Argument definitions

HttpObjectGetHeaders is usually called in a server program.

This code outputs all headers and their corresponding keys.

  ; HttpObjectGetHeaders
  include "omhttp.xin"
  
  process
     local HttpRequest my-Request
     local HttpResponse my-Response
     local stream request-Headers variable
     local stream response-Headers variable
  
     HttpObjectGetHeaders my-Request into request-Headers
     HttpObjectGetHeaders my-Response into response-Headers
  
     output "Request headers:%n"
     repeat over request-Headers
