Content-TypeNone

"Content-Type: None" means that a web server or client is indicating there is no specific format or type of data being sent or received. Normally, with web data, the Content-Type header specifies whether the content is, for example, HTML, JSON, or plain text. When it is set to "None," it signals that no particular content type is defined, which may occur in situations like empty responses or when the data format isn't specified. This helps systems understand how to handle or interpret the data, or recognize that no content needs processing.
