Redirect if record exists is displaying value in address bar

Question

I setup a simple login page to insert record if it doesnt
exist, and
redirect if it does..
since its a login page, i dont want the values past in the
address bar as if
it was a querystring....
i dont recall this occuring in past setups like this..
here is an example of what i see in the address bar
http://corp01/thankyou.asp?requsername=123456789
the form i have setup to do this is set to the following:
Method = POST
Enctype is blank
Action = <%=MM_editAction%>
Target = empty
Class = empty
Is there anyway to prevent this from displaying in the
address bar?
Since the live form will be setup behind a https:// and
security in place..
i want to make sure i code correctly now before we have the
site live...

Answer 1

so the problem is here if the option is equl No categories
found I want to go by id but by subId
so it should look like this
details3 = new
Spry.Data.XMLDataSet("prog.cfm","progs/prog[id="+window.activeRecord+"]",
{useCache:false, loadInterval:1660});
Also I tried to write some code but i do get the wrong result
function hielo3()
if(window.activeRecord2 == null || window.activeRecord
==null)
alert("You must select a category or a subcategory!Please go
back to the category Tab");
setTimeout('tp1.showPanel(1);',0);
return false;
} else if (window.activeRecord2="No subcategories found"){
details3 = new
Spry.Data.XMLDataSet("prog.cfm","progs/prog[id="+window.activeRecord+"]",
{useCache:false, loadInterval:1660});
details3.addObserver(myTab2Observer2);
} else {
//here make your other query to get the details of the
selected option! I am reusing the previous one.
details3 = new
Spry.Data.XMLDataSet("prog.cfm","progs/prog[subId="+window.activeRecord2+"]",
{useCache:false, loadInterval:1660});
details3.addObserver(myTab2Observer2);
