to redirect, proxy, irule or suggest something else

I have a request to serve various content from a different pool for our site to help transition to new cms. Basically:

http://www.abc.com/ -> http://www2.abc.com/

http://www.abc.com/de -> http://www2.abc.com/de

http://www.abc.com/fr -> http://www2.abc.com/fr

http://www.abc.com/es -> http://www2.abc.com/es

http://www.abc.com/pt -> http://www2.abc.com/pt

The dev has expressed that they want an exact equal match of "/" or "/de", etc., to pull from the pool that serves content for www2 (varnish cluster that fronts a cms). They do not want www2 to be apparent to the end-user.

I've tried a couple things (to test with only "/" at first):

when HTTP_REQUEST {

if { [HTTP::host] eq "www.abc.com"} {

if { [HTTP::path] starts_with "/" } {

pool pool-www2.abc.com

}

}

}

Or:

when HTTP_REQUEST {

if { [HTTP::host] eq "www.abc.com"} {

switch [HTTP::uri] {

"/" -

"/index.php" -

"/pt/" -

"/de/" -

"/fr/" -

"/es/" -

"/pt/index.php" -

"/de/index.php" -

"/fr/index.php" -

"/es/index.php"

{

pool pool-www2.abc.com

}

}

}

}

There are number of other urls, such as /foo, /meh, /bar (and language urls, i.e. /pt/foo/, /pt/meh, /pt/bar/) they do not want "redirected", only the main page for each language. Any thoughts/suggestions? not even sure this is possible or sane :)
