Flask nocache decorator.

        
        
        
    
from flask import make_response
from functools import wraps, update_wrapper
from datetime import datetime

def nocache(view):
    @wraps(view)
    def no_cache(*args, **kwargs):
        response = make_response(view(*args, **kwargs))
        response.headers['Last-Modified'] = datetime.now()
        response.headers['Cache-Control'] = 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0, max-age=0'
        response.headers['Pragma'] = 'no-cache'
        response.headers['Expires'] = '-1'
        return response
    return update_wrapper(no_cache, view)

Use it wisely.

        
from nocache import nocache

@app.route('/my_endpoint')
@nocache
def my_endpoint():
    return "Endpoint without cache"
