title: Can I send binary data directly over HTTP?
body: <p>I mean, can I expect to work</p>
  
  <pre><code>POST / HTTP/1.1
  Content-Type: application/octet-stream
  Content-Length: 27
  
  [27 bytes of binary data]
  </code></pre>
  
  <p>And the binary data is arbitrary binary data, not Base64 encoded with <em>all</em> 8 bits in use, not 7 bits. The receiving application is custom application that would know what to do with the data.</p>
  
  <p>Of course, I could test, but I need to know if this is likely to work with real server and over web, not just between both client and server running on a localhost.</p>
