From fe48161dbc7511220b0b91b06c26d2beba7a6586 Mon Sep 17 00:00:00 2001 From: Ingela Anderton Andin Date: Wed, 30 Sep 2015 10:24:35 +0200 Subject: inets: Add new customize function response_default_headers This enables the user to provide default HTTP header values for headers that should always be sent.
