title: Create S3 folder alias or redirect url path to S3 folder
body: <p>Is it possible to have an alias for a folder in S3 bucket?</p>
  
  <p>Here's what I'm trying to achieve:
  I want to host a website with documentation of various projects and upload documentation for new versions of these projects to folders in S3 bucket.</p>
  
  <p>Bucket content would be something like this:</p>
  
  <pre><code>&lt;projectA&gt;
  |---&lt;0.1.0&gt;
      |---index.html
  |---&lt;0.2.0&gt;
      |---index.html    
  &lt;projectB&gt;
  |---&lt;1.0.0&gt;
      |---index.html
  |---&lt;1.1.0&gt;
      |---index.html
  index.html
  </code></pre>
  
  <p>Now I'd like the newest version of any project to be aliased as 'latest'. So when I upload version 1.2.0 of projectB I remove alias 'latest' from version 1.1.0 and add the alias to newly uploaded '1.2.0'.</p>
  
  <p>And url to index page of <code>projectB/1.2.0</code> would be <code>xxx.cloudfront.net/projectB/latest/index.html</code></p>
  
  <p>Is something like that even possible? Maybe with some redirects in cloudfront? (or route53)</p>
