Flash post to asp

Hello.
I want to post data from a Flash page to an aspx file.

This was my first actionScript try.
 var my_lv:LoadVars = new LoadVars();
 my_lv["pName"] =  PL1getName;
 my_lv["pScore"] = PL1getScore;
  // Maybie i need this?   my_lv.addRequestHeader(headerName,headerValue)
 my_lv.send("http://127.0.0.1/testSite/WebForm1.aspx",
"_Blank", "POST");

I found this in this forum and have tryed diffrent ways but it dont send a
request for page at all..

So then i tryed this....
 getURL("http://127.0.0.1/testSite/WebForm1.aspx?pName=" +
Pl1getName,"_Blank", "POST")

Yes this opens the page and sends the name but this is easy to manipulate...

Here is my ASP code for geting the data.
 if(Request.Params["pName"] != "")
  Label1.Text = Request.Params["pName"];

I know you think this should be posted on a flash forum page , but i think you
guys here can aswer the question better because the first code is the right way
to conect to PHP. And there must be a way in asp to recieve this information
too. (or to hide info in the getURL command) I will be happy if someone can
help.

Greetings  Jørgen
