Content-type:
MIME types are standard, case-insensitive strings that identify a data type, used throughout the Internet for many purposes.
They start with the general type of data (like text, image, or audio), followed by a slash, and end with the specific type of data (like html, gif, or jpeg). HTML files are identified with text/html, and GIFs and JPEGs are identified with
- image/gif and image/jpeg.
