title: Get MIME type with Scrapy
body: <p>I just want to get the MIME type of an URL with Scrapy. I will process files in different ways according to the file type, so I need to know which type of file I downloaded.</p>
  
  <p>Is MIME type in any variable or in Scrapy Response object?</p>
  
  <p>I don't want to recognize a file by the extension since many images on Internet don't use it, example: . I want to use MIME and extensions.</p>
