When the --anticache option is passed to mitmproxy, it removes headers
(if-none-match and if-modified-since) that might elicit a
304 not modified response from the server. This is useful when you want to make
sure you capture an HTTP exchange in its totality. It's also often used during
:ref:`clientreplay`, when you want to make sure the server responds with complete data.
