Request ID visible

Hi!

We are using EG21-G and trying to troubleshoot outgoing https request. Is there a way to read the request ID from modem what was used in GET request it generated towards server?

Is it possible to manipulate automatically filled Request ID value by configuring <request_header> to 1? Or is this 1.5.1. Customize HTTP(S) Request Header concept (in HTTPS Apllication Note) only for creating additional customized headers?
