A page parameter is a named value that one page can pass on to another. A page parameter can be set to a component property, another parameter, or a constant value. Page parameters are typically appended to a URL as query strings or are submitted with a form. Tags that invoke other pages, such as dsp:a and dsp:include, can set these query strings. A JSP can explicitly define its own page parameters through the tag dsp:param. An included page also inherits the page parameters of its parent page.
