i dont use any mysql queries for the external db. i send xml via post
and getting pack xml. this xml is parsed into an array and merged into fe_user->user
it seems for me, that somewhere in realurl are funktions wich are producing many many request
to initFeUser. Maybe for chaching, pagetree or something else?
does something like syspage is uses wich checks with initfeuser?
