title: Create Temporary Webpage with Randomly Generated URL
body: <p>Alright, so I'm trying to write a little app that creates a temporary webpage (kinda) and I can't figure out what it is that needs to happen for this to work exactly.</p>
  
  <p>Let me explain what I'm trying to do and that should help. Basically, I want to have <code>app.com</code> and when a user goes there there's a button like "Make temp page" or something. Click that and then it makes a random URL extension and puts the visitor there, so something like <code>app.com/admin/xxyy12</code>. Now the user can give the URL <code>app.com/xxyy12</code> to someone and they can navigate there and send data back and forth between each other, my thinking was via WebSockets. So I want the person that made the link to be an admin of sorts and when they leave that "admin" page I want it and <code>app.com/xxyy12</code> to self destruct basically, no one can go there and that route doesn't exist anymore.</p>
  
  <p>Is this possible and what technologies should I look into to accomplish this? I thought it would be cool to do this all in-browser with no server, which kills some security but I don't really care about that. I'm not really sure how to create these "temporary" pages either. I figured WebSockets would come in handy to send data between the person that created the link and the client visiting it, and I figured the main page <code>app.com</code> would need a socket to the user at <code>app.com/admin/xxyy12</code> to determine when it disconnects. Also, I considered html parameters to basically make a "temporary" URL that would just read the param and then that would wire the client to the URL creator. There would also need to be a way of storing what active temporary pages exist.</p>
  
  <p>I recognize that this question is rather vague but I suppose I'm just looking for ideas of how to accomplish this and what technologies would be recommended. Thanks for any and all help.</p>
