I know it's possible because I remember a programmer helped me with this about like 15 years ago or something.
Imagine someone logs in to a password protected page on your website. We'll call that Login #1.
Then within that page, you have another link that says "Go Login Here" and when they click that link they arrive at the new page but are STILL logged in to what they were logged into already.
What can I put in the url string that when they click the link, the user is "cleared" from their login of the page they were logged into and brought to another page with a username and password login page when they click on link so that Login #2 displays?
