HTTP_X_FORWARDED_FOR does not exist when using custom script

[davama]

NetBox version

v3.0.10

Python version

3.8

Steps to Reproduce

Background: #7876

python snippet:

        remote_ip_address = self.request.META.get('HTTP_X_FORWARDED_FOR') or self.request.META.get('REMOTE_ADDR')
        self.log_info(f"Running as user {remote_username} (IP: {remote_ip_address})...")
        self.log_info(repr(self.request.META))

my nginx snippet:

    location / {
        proxy_pass http://127.0.0.1:8001;
        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
	proxy_set_header X-Forwarded-For $remote_addr;
    }

Expected Behavior

{'CONTENT_LENGTH': '503', 'CONTENT_TYPE': 'multipart/form-data; boundary=----WebKitFormBoundaryw66ayIoNmlX9BFq7', 'HTTP_ACCEPT': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9', 'HTTP_ACCEPT_ENCODING': 'gzip, deflate, br', 'HTTP_ACCEPT_LANGUAGE': 'en-US,en;q=0.9', 'HTTP_HOST': '127.0.0.1:8001', 'HTTP_REFERER': 'https://netbox-lab.nwk.jwm2.net/extras/scripts/netbox.AddDevice/', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'POST', 'SERVER_NAME': '127.0.0.1', 'SERVER_PORT': '8001', 'HTTP_X_FORWARDED_FOR': 'x.x.x.48'}

HTTP_X_FORWARDED_FOR should be present as nginx set it.

Observed Behavior

The above would give me the below output:

{'CONTENT_LENGTH': '503', 'CONTENT_TYPE': 'multipart/form-data; boundary=----WebKitFormBoundaryPrHAvPRqa4n0y5Bn', 'HTTP_ACCEPT': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9', 'HTTP_ACCEPT_ENCODING': 'gzip, deflate, br', 'HTTP_ACCEPT_LANGUAGE': 'en-US,en;q=0.9', 'HTTP_HOST': '127.0.0.1:8001', 'HTTP_REFERER': 'https://netbox.domain.com/extras/scripts/netbox.AddDevice/', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'POST', 'SERVER_NAME': '127.0.0.1', 'SERVER_PORT': '8001'}
