What is a MIME type?
A MIME type (Multipurpose Internet Mail Extensions) is a standard that indicates the nature and format of a document, file, or assortment of bytes. It is used by browsers and servers to determine how to handle content.
How are MIME types structured?
A MIME type consists of a type and a subtype separated by a slash (e.g., text/html). The type represents the general category, and the subtype identifies the specific kind of data.
Can one file extension have multiple MIME types?
Yes, some file extensions can be associated with multiple MIME types. For example, .xml can be text/xml, application/xml, or application/xhtml+xml depending on the context.
What is the difference between MIME type and Content-Type?
The Content-Type HTTP header uses MIME types to describe the data being sent. They are essentially the same thing — MIME type is the standard, Content-Type is the HTTP header that carries it.
