I want to set all of my http headers responses to something like this:
response.headers["X-Frame-Options"] = "SAMEORIGIN"
I checked this question, but it only changes the header for one specific controller. I want to change all of my headers maybe in “before_request” function similar to the following logic. How can I do that?
@app.before_request def before_request(): # response.headers["X-Frame-Options"] = "SAMEORIGIN"

Set the header in a @app.after_request()
hook, at which point you have a response object to set the header on:
@app.after_request def apply_caching(response): response.headers["X-Frame-Options"] = "SAMEORIGIN" return response
The flask.request
context is still available when this hook runs, so you can still vary the response based on the request at this time.
