When a user visits any web page, save the page name and URL in the session as an array of objects. Each object should contain the page name and URL. Create a footer.ejs file to display the list of the 10 most recently visited pages in the footer of every EJS page. Each page should appear as a clickable hyperlink in a separate row. If the user clicks on a link, the corresponding page should open. At the end of the list, include a "Remove All" link to clear the list of recently visited pages in the session. Add an "X" next to each link to allow the user to remove that specific page from the session. After removing a page or clearing the list, redirect the user to the /home page. If a user visits a page that is already in the list, move it to the top and remove the previous occurrence to avoid duplicates.
