What is HTTP headers lookup?

HTTP headers lookup is the process of examining the HTTP headers sent by a client (such as a web browser) to a server, or the headers sent by a server in response to a client request.

HTTP headers are pieces of information that provide additional context and instructions to the server or client about how to handle the request or response. For example, HTTP headers may include information about the type of content being requested or served, caching instructions, security information, and more.

There are a variety of tools available for performing HTTP headers lookup, including browser extensions, command-line utilities, and online services.
