Flask url_for() no cache
I wrote a blog post about this a while ago.
Basically, you need to create a response to send, then set some extra headers on the response, then send the response:
def send_url(method): response = app.make_response(url_for(method)) response.headers.add('Last-Modified', datetime.datetime.now()) response.headers.add('Cache-Control', 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0') response.headers.add('Pragma', 'no-cache') return response
Disabling all caching just because once in a while you have a new release is really not good practice. Caching of css and js gives huge performance benefits.
What good sites do is to add a timestamp of the file to the resource URLs. For example, in Flask, here is a way to do this transparently: http://flask.pocoo.org/snippets/40/
