What is a MIME type?

The MIME type (Multipurpose Internet Mail Extensions) is a standard that was proposed by the Bell Communications laboratories in 1991 to broaden the possibilities of email, involving insertion of documents (images, sounds and text) into a message.

Since then, the MIME type is used to format both documents attached to a message and documents transferred by the HTTP protocol. Thus during a transaction between a web server and an internet browser, the web server first sends the MIME type of the file sent to the browser, so that the browser knows how to display the document.

A MIME type is comprised as follows:

Content-type: main_mime_type/mime_sub_type
A GIF image, for example, has the following MIME type:
Content-type: image/gif
