I&#x27;ve been trying to design something along these lines now that Firefox aggressively prunes history with no user override ( it keeps barely five days worth on my laptop ).<p>However the main challenge is that much of the web is now SSL, so a light caching proxy isn&#x27;t feasible unless it does MiTM which I don&#x27;t want.<p>My current idea is to log DNS lookups but that doesn&#x27;t, of course, provide page content data.
