This tool allows you to analyze and extract information from HTTP headers of a request or response. Simply paste the headers in the editor above, separated by a new line, and the tool will automatically extract the header names and display their descriptions and examples.
HTTP headers are the core part of HTTP requests and responses. They carry information about the client, server, request, and response. They are key-value pairs that are separated by a colon. The header name is case-insensitive, while the header value is case-sensitive. Headers are used to pass additional information between the client and server. They can be divided into two categories: request headers and response headers.
Request headers are sent by the client to the server, while response headers are sent by the server to the client. Some headers are common to both requests and responses, while others are specific to either requests or responses. Headers can be used to control caching, authentication, security, and other aspects of the HTTP protocol.
