Content-Type Header: Understanding HTTP Data Formats

Content-Type is a header field in HTTP (Hypertext Transfer Protocol) which specifies the media type or format of the data in the HTTP message body. It tells the receiving system what type of data is being sent so that the system can understand how to interpret and process the data. The Content-Type header is essential for communication between clients and servers, particularly when transmitting data such as text, images, audio, video, or binary files. The field value consists of a media type and subtype, separated by a slash (/), and may also include optional parameters such as character encoding, language, and boundary. Common Content-Type values include 'application/json', 'text/html', 'image/jpeg', 'audio/mp3', 'video/mp4', and 'multipart/form-data'.
