Microsoft Learn. I first noticed this a couple years ago not long after they changed the url from docs.microsoft.com to learn.microsoft.com. Each time you went from a google search to a learn page it would load, redirect to login.microsoftonline then go back to the learn page. Hitting back in the browser took you back to login.microsoftonline which forwarded you back to the learn page. Hitting back twice in quick succession took you back to the docs page then forwarded you to login.microsoftonline. Easier to close the tab and start again. Maybe it was something to do with the changes to the site to make it more like an online college, as that portion requires signin, but I’m just after first party doco! Dunno if this still happens today but at the time I was browsing docs every other day and it was super frustrating. Note: it only did this if you were already signed in elsewhere, something triggered Microsoft sso check. Similar to if you go to portal.office.com, it is a page that requires sign in and so does the login.microsoftonline redirect to check for active tokens.
