Presidential candidate Bernie Sanders is one of a few candidates customizing error pages on their campaign websites.
Vermont Public Radio reports the state's senator customized his 404 page, which pops up on a webpage if a user enters an address for a page that doesn't exist.
Users who reach the 404 page will see a video of Sanders telling them they're at the right website, but wrong page. He then prompts the user to scroll to the bottom to take them to the correct page.
