Request Object Example
The request object is created for each request and once the response is submitted then it gets destroyed. The request object is used to pass the information from one page to the other page if the pages are getting invoked during the request lifecycle. The below example will print all the request attributes as well as it gets the information passed from outer page to inner page.
