setting header in actionscript

Hi, can anyone help me on this.

I'm trying to set the connection/keep-alive headers but everytime I run the application in the flash player, I always have this error:

ArgumentError: Error #2096: The HTTP request header cannot be set via ActionScript.

Does this mean that setting these headers is not supported for applications for the flash player? Or am I doing something wrong. What I only need is to set the keep-alive and connection headers.

Any help would be greatly appreciated!
