Flex HTTP Support

I'm having some hard times supporting a FLEX client trying to get XML over HTTP from a server of mine. I have a server implemented in ASP.NET MVC framework. It basically uses HTTP GET for data retrieval, and HTTP POST for data updates. I also use HTTP custom headers to determine the view to return to my clients, depending on the type of service.


One of the application clients consumes these over-HTTP services using a Flex client. From the information I got, I need to modify my request-response model, since Flex HTTP service has these limitations.


Did anyone come across these issues? Any workaround / suggestion?
