we have 3 machines
one that have data on it (machine1)
one that is a webserver that contains flex application that access data on machine1 and has crossdomain file on its server root (machine2)
and the last one machine3 serves as a client that requests pages from machine2 .
the problem that machine3 can not access data of machine1 through machine2 url for example http://machine2/flexApp/index.html
That's how crossdomain files work. You need a crossdomain file on machine1 granting access to machine2.
