It redirects the user corresponding to the domain name of the current page.
If you are on domain name of geeksforgeeks as https://www.geeksforgeeks.org/
then it will take you to https://www.geeksforgeeks.org/BASIC/testpage.html and
if you are on http://google.com/ then it will take you
to http://google.com/BASIC/testpage.htmlIII is valid because it takes you to the page corresponding to the
current url of the page. Please note that if we use / before testpage.html,
then it is respect to domain not the complete url.IV is valid because it takes you to the container with class/name as
test on the same page.这个问题的测验
