# app.config['SEND_FILE_MAX_AGE_DEFAULT'] = 0

def dir_last_updated(folder):
    return str(max(os.path.getmtime(os.path.join(root_path, f))
                   for root_path, dirs, files in os.walk(folder)
                   for f in files))

@app.route("/", methods=["POST", "GET"])
def home():
#   Get the current path of the program
    path = os.getcwd()
    path = path.replace('\\', '/')
#   Now you set last_updated to the last cache
    return render_template("index.html", last_updated=dir_last_updated(path+"/static"))
