Big-ip in the middle fo SSL

Okay, so is it safe to say that decryption and re-encryption is working, and that the server is now just complaining about a URI?

If so, do you need to just append the URI to the request if it doesn't exist:

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/" }
        HTTP::uri "/uri1"
    }
}

or actually redirect the user to the new URI:

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/" } {
        HTTP::redirect "https://[HTTP::host]/uri1"
    }
}

The first will transparently replace the URI on its way to the server using HTTP::uri, and the second will physical redirect the user to a new URL using HTTP::redirect.

I'm not quite sure I understand yet where uri1 and uri2 fit into all of this.
