Thanks for the followup. One of the main things I try to use
my proxy for is to cache semi-static content like fonts and scripts to
minimize or eliminate requests for the same resources but from different
sites so owners of those resources may not be as easily able to track a
user as they move across the web.
In HTTP/1.1 and later the server is explicitly passed headers from the
clients request to check whether the cached entry can be used. So
forcing caching will not help with your requirement. Caching is purely a
bandwidth saving and (usually) performance improving measure.
For tracking prevention you need to filter out the details (eg headers)
which servers use for that tracking and fingerprinting.
