Hello Iñaki,
I did this a long time ago using a db backend, i can't remember exactly how.
the table would be:
areacode, route
1 route1
13 route2
I connected to mysql and ran something like:
select * from routes where '$rU' like concat(areacode,'%') order by
len(areacode) desc limit 1;
that works perfectly
hope it helps
David
