Browser caching issues in flask

Question

I have built a website using flask (www.csppdb.com). Sometimes when I log in as one user, log out, then login as another user I still see pages from the first user I logged

Answer 1

Setting the cache to be max-age=0 fixed it.

@app.after_request
def add_header(response):
    """
    Add headers to both force latest IE rendering engine or Chrome Frame,
    and also to cache the rendered page for 10 minutes.
    """
    response.headers['X-UA-Compatible'] = 'IE=Edge,chrome=1'
    response.headers['Cache-Control'] = 'public, max-age=0'
    return response
