Well that is the problem, the caching should be configurable in the
sitemap and not the xconf since IMO we should be able to use caching and
non-caching locationmap lookups. *Without* restarting forrest. ;-)

No, please let it on, but maybe give us some instructions how we can
configure it on a sitemap level (best as <map:pipe/>).

> Now that we are using the locationmap extensively it is showing up just how innefficient
it is. The problem is that for the majority of requests there are multiple reqeuests to the
locationmap. We can make things much faster (especially on the first page request) by caching
results in the locationmap.

as a key and, of course, the location as the value.
> If we test all locationmaps and find no result we should record that tere is no result
in this hashmap. This will also be a good place to throw an exception so that Cocoon can better
report such errors (see FOR-701)
