My website is hosted on Google App Engine using Standard Python.
In request handlers, I am setting HTTP header "cache-control: max-age=3600, public" So frontend server "Google Frontend" caches the response for 1hr(which I want to save cost). In rare cases the content of page changes and I want the content in frontend cache to be invalidated. How can I do that? Is there any API for it? I can't alter the URL as they have 90% traffic from Google Search. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
