How can I navigate to a url programmatically with a correct referer header?

I have a flex application that uses the actionscript navigateToURL function to go to another system. However, a third party app that needs to be integrated checks for valid links by looking at the HTTP referer header, and it seems like that header is blank when using a navigateToURL call.





Is there a way in actionscript or javascript to programatically generate a url and go to it with a correct referer header?

    Aaah the referer header. I had a lot of frustration from this.

    Long story short, in Flex+AIR, no matter what you do (ex: manually change headers) the referer will ALWAYS be overwritten by the framework. I never actually tried it inside a browser (i.e. : not in AIR) so I can't confirm it behaves the same. You can try for yourself if you want by adding a new header to an URLRequest object like this :

    var request:URLRequest;
    request.requestHeaders.push(new URLRequestHeader("referer", "myReferer.com");


    Here's a bunch of interesting links confirming what I'm saying. I suggest you vote for the idea on Adobe Labs Ideas and comment on the bug on Adobe bugbase

Slow Android emulator

By User
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
