Intrusion, you put it in a Wowza module.
They're talking about this module: http://www.wowzamedia.com/forums/con...-your-SWF-file
Edit: I see in your other post you're already using the module. We should get shamrock's input on this since he seems to have another solution. But, you could do it like this:
queryString = client.getQueryStr();
reject = false;
//Add the above before the following part in the Hotlink Denial module
reject = true;
