title: Rails - Back button generates duplicate server requests
body: <p>I just encountered a strange behaviour in my current RoR web app: every time I use the browser's back button (multiple browsers tested, safe mode included), the GET request is being sent multiple times, duplicated. Sometimes twice, but up to 5 times in a row in under 3 seconds. This also causes the SQL queries to run multiple times, doing the same thing.
  If I use links to go back, or paste URLs to access the previous page, this does not happen. 
  Did anyone encounter this, or know what could cause it? </p>
  
  <p>Thanks for your help! </p>
  
  <p>Best, </p>
