missing `-d` usage

Also, for setting `Content-Length` I had to use the below script,
should we add this as well
or at least put it in a README?

$ cat afc_server_sim.sh
#!/bin/bash

# Define the JSON content
json_content=$(cat afc-reply.json)

# Calculate the length of the JSON content
content_length=$(echo "$json_content" | wc -m)

# Create the HTTP response
http_response="HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: $content_length

$json_content"

# Write the HTTP response to a file
echo -e "$http_response" > response.txt

# Use netcat to listen on a specific port and send the response to any
incoming requests
while true; do nc -l 9999 < response.txt; done
### END OF SCRIPT##
and then I run `sudo ./afcd -u http://localhost -p 9999 -ddd`
