What are HTTP Headers?
HTTP headers are essential components of HTTP requests and responses. They convey vital metadata about the request or response, such as content type, server information, caching policies, cookies, security policies, and more. Inspecting these headers helps developers understand how web servers communicate and how browsers interpret web pages.
