title: How to return to previous URL after clicking on "Back" button in Rails
body: <p>I'm using simple_calendar in my Ruby on Rails project and I'm having a problem.</p>
  
  <p>When I see "February" my URL looks like this:</p>
  
  <pre><code>localhost:3000/meetings?start_date=2016-02-07
  </code></pre>
  
  <p>After I "Edit" an event, I am redirected to the "Show" page of that event where I have a "Back" button.
  When pressing that button, I'd like to return to the same month's URL I was at before. Instead of that, I return to:</p>
  
  <pre><code>localhost:3000/meetings
  </code></pre>
  
  <p>How do I return to the first URL?</p>
