Note:
It doesn’t ping the entered URL to check if the URL is actually present or not. It simply checks to make sure the user entered information starts with http:// and ends with a dot followed by a valid TLD.
If viewed on a HTML5 compatible mobile browser, it pops up custom keyboard to facilitate the user to enter URL.
