Application server	Runtime behavior
ASP	Accesses either the QueryString or the Form collection of the Request object: When the METHOD attribute of a <FORM> is GET (or when data is passed directly in the HREF attribute of an <A> element), GetParam accesses the specified parameter in the QueryString collection. When the METHOD attribute of a <FORM> is POST, GetParam accesses the specified parameter in the Form collection.
JSP	Calls the getParameter method on the request object.
