Answer 1

While the answer of NikitaBaksalyar is pointing into the right direction. I had trouble getting it to work. The page code gave me an error with missing response.

The solution is quite simple. Use the make_response method.

from flask import make_response

For per page cache-control settings:

    @app.route('/profile/details', methods=['GET', 'POST'])
    def profile_details():
        ......
        response = make_response(render_template('profile-details.html'))
        response.headers['Cache-Control'] = 'no-cache, no-store, must-revalidate'
        response.headers['Pragma'] = 'no-cache'
        return response

Default cache-control settings:

    @app.after_request
    def add_header(response):
        response.headers['X-UA-Compatible'] = 'IE=Edge,chrome=1'
        if ('Cache-Control' not in response.headers):
            response.headers['Cache-Control'] = 'public, max-age=600'
        return response
