Trouble sending vars from Flash to ASP

This is what I need to be in the header of the loadVars send functionality

http://168.103.142.125/cryobase?SQL=spUpdatePosition%20101,102,417

I can get that exact tracing my sendLoadVars variable that Flash is sending but I am getting:

http://168.103.142.125/cryobase?SQL=spUpdatePosition%20101%2C102%2C417
Which is adding “25” after the “%” and the commas are coming out as %C. This needs to be exactly as above for my client. Please help

The code is as follows:
var sendLoadVars:LoadVars = new LoadVars();

var sendString:String = new String;
sendString = "spUpdatePosition"+"%20"+objectOutputNode+","+objectOutputX+","+objectOutputY;
sendLoadVars.SQL = sendString;
trace(sendLoadVars);
sendLoadVars.send("http://168.103.142.125/cryobase","_blank","GET");
