HTML Response and Content Types

HTTP Response and data stream


The HTTP protocol has two main phases of communication:
  • HTTP REQUEST;
  • HTTP RESPONSE.
The HTTP response is a single data stream, so when you ask for a web page containing images, embedded in the stream there are links to resources (as images) that need additional requests. The browser has the responsibility to make these requests.

Content-Type


An HTTP response has got many HTTP headers. One of these is called Content-Type. It specifies what type of file that has been sent by the server and it's used by the browser to process the data stream.
Here are the most common content types:
  • text/html: HTML;
  • application/octet-stream:Arbitrary binary data;
  • application/zip: ZIP archive files;
  • image/jpeg: Images files;


Is it possible to make an HTTP response with different content types?


If you want to send different files you should use a ZIP file.
