The normal behaviour is one request per page/frame and one instanciation
of request tools per request. If this is not what you observe, you can
investigate.

Your suspicion is true only if Struts/Tiles, which I don't know, is
implemented using frames/iframes.

I take profit of this mail to let us speak a bit about tools (more for
devs).

We spoke before about tools pooling (especially Nathan iirc): how can it
be implemented? Using a Reusable interface with a reinit(initdata)
method?

And a suggestion on the same subject:

Maybe we could have the syntax of the scope element be:
application | session | request | <url regexp>
in toolbox.xml to refine scopes at a thiner level than the request
scope.
