HTTP headers lookup

HTTP Headers are name/value pairs that appear in HTTP requests and responses. They are used to pass information about the requestor, the requested resource, the server, and the response itself. HTTP headers can be used for various purposes, including authentication, caching, and redirection. To get all the HTTP headers that an URL returns for a typical GET request, you can use a HTTP headers lookup tool. This tool will return the headers for the URL you specify and the headers for any related resources (such as images). By examining the HTTP headers, you can better understand how the server is handling your request and what kind of information is being passed back to you. Our HTTP headers lookup tool is free to use, and you can get started by entering an URL into the input box.
