and exit from script execution :(

If a host responds for too long, the script can return an error - I'll try to suppress all the exceptions that the requests module returns so a script can move on to another js file.

Hi, I fixed it with

try:
            js_file_status = requests.get(line, verify=False).status_code  ## finding out a status code of js file url
        except Exception:
             pass

Closing now.
