How to make a checksum for pull region page?

Question

In my application, I use a region where I pull different pages' content when user presses this or that button. I would like to put a session-state security on these pages (arguments must have checksum) to prevent direct access to them, but can not imagine how to put checksum on arguments when using htmldb_Get ?

Answer 1

Does not work :o((
"This page cannot be invoked using a URL or using a GET or POST to the show procedure, it must be called using a "Branch to Page" branch type. "
The region is pulled by the following function:
function dhtml_GetDetail(pPage){
var reg = $x('ReportDrop');
var get = new htmldb_Get(null,$x('pFlowId').value,null,pPage);
get.add(field_name , field_value);
gReturn = get.get(null,'<htmldb:BOX_BODY>','</htmldb:BOX_BODY>');
get = null;
var newdiv = document.createElement("div");
newdiv.innerHTML = gReturn;
reg.replaceChild(newdiv, reg.firstChild);
return;
}
