## Sticky cookies - command-line: _-t_ (sticky cookies on all requests) - command-line: _-T filt_ (sticky cookies on requests matching filt) - mitmproxy shortcut: _t_ When the sticky cookie option is set, __mitmproxy__ will add the cookie most recently set by the server to any cookie-less request. Consider a service that sets a cookie to track the session after authentication. Using sticky cookies, you can fire up mitmproxy, and authenticate to a service as you usually would using a browser. After authentication, you can request authenticated resources through mitmproxy as if they were unauthenticated, because mitmproxy will automatically add the session tracking cookie to requests. Among other things, this lets you script interactions with authenticated resources (using tools like wget or curl) without having to worry about authentication. Sticky cookies are especially powerful when used in conjunction with [client replay](@!urlTo("clientreplay.html")!@) - you can record the authentication process once, and simply replay it on startup every time you need to interact with the secured resources. ## Sticky auth - command-line: _-u_ (sticky auth on all requests) - command-line: _-U filt_ (sticky auth on requests matching filt) - mitmproxy shortcut: _u_ The sticky auth option is analogous to the sticky cookie option, in that HTTP __Authorization__ headers are simply replayed to the server once they have been seen. This is enough to allow you to access a server resource using HTTP Basic authentication through the proxy. Note that __mitmproxy__ doesn't (yet) support replay of HTTP Digest authentication.
