May be you need to make use of domian IP Addresses form where the request has come. May be you can make use of crossdomain file and allow access to only particular based on their IP Address and restrict others.
Thanks for your reply, i am using BlazeDS for RemoteObject communication using mypolling-amf and also WebServices with proxy set to true . I do not have any crossdomain.xml file as Blazeds takes care of the crossdomain.xml. If i define a crossdomain file how do i point the application to use that.
If you use apache web server you can restrict based on IP address.
But if the permitted user is logged in to a different computer, he might not be able to access the application if it is restricted by IP address.
