The HTTP Accept header is a request type header. The Accept header is used to inform the server by the client that which content type is understandable by the client expressed as MIME-types. By using the Content-negotiation the server selects a proposal of the content type and informs the client of its choice with the Content-type response header. If the Accept header is not present in the request, then the server assumes that the client accepts all types of media.
Accept: <MIME_type>/<MIME_subtype> | <MIME_type>/* | */*
Directives: This header accept below mentioned directives:
- <MIME_type>/<MIME_subtype>: This directive holds the type/subtype of the web content that the client will received by content-type header which is chosen by the server from Accept header. Basically it holds the single mime type like text/html.
- <MIME_type>/*: This directive holds the type but can accept any subtyping like image/* means the image can be jpg, png, or can svg everything will be accepted.
- */* This directive accepts any kind of type/subtype.
