AS3 Tip of the Day - flashvar

I'm creating an web flash application which requires SESSIONs if the user is login or not.

How I do it? I simply used a "flashvar" to detect if the user is login or not.

to get the parameters in flashvar see sample:

in HTML:

src="testflashvar.swf"

quality="high"

bgcolor="#000000"

width="500" height="300"

flashvars="userid=mykhel trinitaria"

name="testflashvar"

align="middle"

play="true"

loop="false"

quality="best"

allowScriptAccess="always"

type="application/x-shockwave-flash"

pluginspage="http://www.adobe.com/go/getflashplayer">

in FLASH:

var userid:String = root.loaderInfo.parameters.userid

trace(userid); // "mykhel trinitaria"
