Hi, Yves, thanks for reply, I really wanted this, ;)

ok, This is to be used just as a connector to /servlet, and, I tested all things with Jigsaw and for me the MirrorFrame works fine, but I have some doubts, that I explain follow:

First how I configured the Mirror:
In Docs space I added org.w3c.jigsaw.resources.VirtualHostResources.
   (following the tutorial "How to setup virtual hosting in Jigsaw?" but on step 5 i added a org.w3c.tools.resources.FramedResource)
On FramedResource I added the org.w3c.jigsaw.proxy.MirrorFrame then on MirrorFrame I added org.w3c.jigsaw.filters.CacheFilter.

worked fine, but this is the best way to configure a mirror?

is the org.w3c.jigsaw.filters.CacheFilter that maintain the static pages or is the org.w3c.www.protocol.http.cache.CacheFilter configured in Properties / Proxy / filters?

Another question, There is a way to have all static content copied in Jigsaw server, and the Mirror only forward /servlet or pages don't found in this directory, then I don't use CacheFilters?
If yes I can develop a downloader that download updates of my site when needed. and remove the Cache Work.

For example:
The client request Index.html that is in your local Jigsaw cache and
returns quickly, in this page has a login form with action /servlet/
that the local Jigsaw forward to an online WebServer (Apache+Tomcat).

1) I don't need that for every request to static content to check the
WebServer if this page has changed, for static content, I like to run a
method like, updateAllCacheNow(). but this situation is for some sites,
don't for all.

Do you want Jigsaw to forward everything and act as a surrogate proxy or
just used as a connector for some spaces like /servlet/ ?
2) for this maybe I use MirrorFrame? or MirrorFrame don't work with
dynamic contents?

MirrorFrame is the one to use in the second case describer. MirrorFrame
mirrors part of a web site and don't really care if the content is dynamic
or not.

3) I need to Implement my own ProxyFrame and CacheFilter, or this
already can be done by Jigsaw?

It should be there, but if there is something it can't do, it can be

4) If I need to Implement there is a way to get the Sequence diagram or
idea of a request on Jigsaw? (how  ProxyFrame and CacheFilter works from
request to response)

The processing model is defined at

Note that there are two different cache filters, one server side and one
client side.
The client-side one is the one to use in the general case for proxies and
mirrors, as it act as an HTTP/1.1 compliant cache. Most probably the
static content will stay in the cache and the dynamic will be always
forwarded (provided they are served with proper HTTP headers)

The idea is to reduce the web traffic, for example, think that in one
page I have 30 images, for all images, the browser cache, request to
Jigsaw Proxy if image changed, then Jigsaw Proxy request to WebServer if
image changed, and only when WebServer reply to JigSaw Proxy the Jigsaw
reply to Browser that image isn't changed, then the image is displayed.

Hum so it is a HTTP/1.1 proxy/cache compliancy issue (in that case only
the ProxyFrame and the CacheFilter). When the browser ask for a new
version, the cache will compare the request with what's in the cache and
the expiration timeand based on that will serve it directly of get it form
the uptream server.

On browser I can't change this behavior but on Jigsaw I can, but I need
some help, before start, to assure that I don't already make a know
feature of Jigsaw.

Well, if the browser is in Java, you can reuse Jigsaw's HTTP stack (and
proxy/cache) in place of the default one.
