HTTPService run only in Flash Builder

Hi to all

I have a web application where I use <s:HTTPService> to retrive record from a table

Now in Flash builder work all perfectly if I generate the bin-release and I copy in a IIS7 server do not work

I read to put in the root web directory of IIS the file crossdomain.xml in this way

<?xml version="1.0"?>

<cross-domain-policy>

  <allow-access-from domain="*" />

  <site-control permitted-cross-domain-policies="all" />

  <allow-http-request-headers-from domain="*" headers="*" />

</cross-domain-policy>

In my case the server IIS7 is not the same server of the HTTPService call, can this cause the problem ?

Thank's in advance
