  -c, --cookie string          Cookie to use for requests
      --crlf-path              Add CRLF payloads to all available paths (ie: site.com/%0Atest.php)
      --delay int              The time each threads waits between requests in milliseconds (default 100)
  -d, --domains string         Location of domains with parameters to scan

  -x, --http-method string     HTTP Method - GET or POST (default "GET")
  -o, --output string          Location to save results
      --skip-crlf              Skip CRLF fuzzing
      --skip-network           Skip network fuzzing
      --skip-scheme            Skip scheme fuzzing
  -s, --slack-webhook string      Slack webhook to send findings to a channel
  -t, --threads int            Number of threads to run ssrfuzz on (default 50)
      --timeout int            The amount of time needed to close a connection that could be hung (default 10)

  -v, --verbose                verbose output

Usage: 
echo "http://url_to_fuzz" | ssrfuzz scan
cat file_of_domains.txt | ssrfuzz scan
ssrfuzz scan -d file_of_domains.txt
