I have a 3rd side that makes a redirect to my VF page (A Force.com Site) with params.
<form id="AFormId" action="A Force.com Site" method="post" target="_parent" enctype="application/x-www-form-urlencoded" > <input id="SuperID" value="123456789"/> </form> <script> document.querySelector("#AFormId").submit(); </script>
Because the params cant be seen in the URL (Security issue) I would like to get it in the server side- Controller.
Is there a way to get the param ("SuperID") in my controller? without another class to expose methods to handle with post\get requests? - Means without a class with @RestResource(urlMapping = 'someUrl').
All I want is to have the params in my controller and manipulate the Data in it.
I prefer the POST method but I will be comforted with the GET method as well.
