title: How do I set the Http Header for a file in an S3 bucket using boto or another tool
body: <p>Using python boto, how can I modify Http Headers?</p>
  
  <p>In my S3 bucket I have a file with name "shop" and since I upload it without file extension, I have to manually set the Http Header: ContentType = text/html</p>
  
  <p>I want to use a python script using boto to set this header for all files that require this. However I cannot find <strong>a method that changes the headers</strong>.</p>
