Subject: New : internal redirects with "cocoon:" URIs
Content-Type: text/plain; charset=us-ascii; format=flowed
Content-Transfer-Encoding: 7bit

Hi team,

I implemented internal redirects using the "cocoon:" pseudo-protocol. 
This is the Cocoon-equivalent to servlet request forwarding.

This means that writing
  <map:match pattern="">
    <map:redirect-to uri="cocoon:/index.html"/>
  </map:match>
will make a recursive call on the current processor to serve 
"index.html" without going back to the client browser.

This is also available in the Redirector used by actions. And as usual, 
"cocoon:/xxx" uses the current sitemap, and "cocoon://xxx" uses the root 
sitemap.

This feature will be especially usefull with the flow engine, since the 
flow script chooses the page that comes next and should be able to call 
this page without losing business data that may be stored as request 
attributes.

This is implemented in org.apache.cocoon.environment.ForwardRedirector 
and used for now only by the treeprocessor (so I didn't update the 
samples to avoid to break them). Integration with the compiled engine 
should be fairly easy, but I'm sooo late on my paid work, so any takers 
are welcome.

Enjoy,
Sylvain
