Hello,

This should not be the issue since it simply adds a request header. And as per the NSE http library description (https://nmap.org/nsedoc/lib/http.html):

body - The full body, after processing the Content-Encoding header, if any. The Content-Encoding and Content-Length headers are adjusted to stay consistent with the processed body.

we are only using the response.body value throughout the script.
