What I don't get: How does the server decide between read and write mode? Does it first do a read mode redirection and then if the result is "all icons requested" it does a write mode? Or is there one indicative icon that will always be delivered?
So there's indeed an "indicative icon" on the start page that is always delivered. If the browser requests the icon when calling the demo.supercookie.me page, the write mode is invoked, but if the icons is already present in the cache the browser does not send a request and read mode is initiated. ~jonas
