What is a Request Header?
Request Headers are fields passed over in the HTTP request header pages. They can include rules and settings to determine how to operate an HTTP transaction.
Some common examples of Request Headers would be:
- Authorization: Send credentials for basic HTTP authentication to give permission for access
- Cookie: Set a cookie to be stored in the browser so we can track state or sessions
- Cache-Control: Tell the browser how long a resource is eligible to be cached and re-used
- Content-Type: Tell a server the MIME type of the body of a request so that the server knows how to parse the data
- Accept-encoding: This request header specifies the encoding that the client supports.
- User-Agent: Provides details about the client application including the software version, application type, operating system etc.
- Expires: indicates the date and time for which the resource maybe considered fresh.
