Flash Player seems to remove some URLRequest parameters by name

hi

 

we suddently started having problems our video player.

 

we use urlrequest.data

 

the code pretty taken example.

 

now theres 1 particular parameter named "videofile" , disappears in firefox works fine in chrome , ie11.

 

if rename parameter "video" works. if rename "videourl" disappears.. strange..

 

even more strange works if install debug flash player of same version ..

 

code example

 

so in below code url when inspected in debug tools network tab show parameters "examplesessionid" , "exampleuserlabel" "videofile" somehow gone.

 

public function urlvariablesexample() {

    var url:string = "http://www.[yourdomain].com/application.jsp";

    var request:urlrequest = new urlrequest(url);

    var variables:urlvariables = new urlvariables();

    variables.examplesessionid = new date().gettime();

    variables.exampleuserlabel = "guest";

    variables.videofile = "intro.flv";

    request.data = variables;

    navigatetourl(request);

  }

 

problem occurs on:

windows 7 , 8.1 @ least

firefox 46.0.1

flash player 21.0.0.213 (but works in 21.0.0.213 debug version)
