everything in org.w3c.www.protocol.http is related to the client side of
Jigsaw, server side, you have org.w3c.jigsaw.http.Request as it is related
to the internals of Jigsaw (this is not the case for the client side,
which can be used standalone). Both inherits from HttpRequestMessage, they
just have specific additions that explain they are in two different

Same as above.

org.w3c.jigsaw.filter.* Contains the server-side filters, while
org.w3c.www.protocol.http.* contains the packages of client side filters
(like ProxyDispatcher, MICPFilter and such).

The first one is called before and after the request is processed, the
client side filter being part of the processing if you are using a proxy.
As always, the client-side part, can be used standalone, and the
client-side cache can provide caching for a browser reusing Jigsaw's
classes, for example.

If you have configured Jigsaw as a proxy, by default the cache filter is
added, you can see it in the properties (Props, in jigadmin).
