How to get response header using ActionScript? (Flash)

S开发者_运维技巧o... I have a URL like www.example.com/stream/

I need to make any request to this url and get Http Rewspons header (like this one:

HTTP/1.0 200 OK
Content-type: video/x-flv
Cache-Control: no-cache

I do not need reponse body at all. After I get header need to emmidiatly close connection to that url (so stop to obtain data from it)

How to do such thing (I use Flash builder)

Aparently, that's possible in AIR (I've never tried it):

The only other way I can think of is using a Socket directly. It's more involved though, and there are some security related issues that are a PITA.
