FlashPlayer and Flex Security Restrictions When Consuming a Webservice

Here our system configuration (scenario):

• Server A: hosts your Flex application
• Server B: hosts a webservice consumed by your Flex application
  

 In order for your Flex application to be able to consume the webservice in above scenario, you have two options:

• Place in the root of the application server on Server B a crossdomain.xml file specifying: allow-access-from-domain: server-A-domain, or
• Use the Proxy service on Server A, which is part of LCDS and BlazeDS dataservices.
