What are HTTP Headers?

HTTP headers are sent along with HTTP requests and HTTP response to send more information in an organized manner.  When a web browser sends an HTTP request it sends 1 or more HTTP headers each with a \r\n seperation.  When the list of headers is done there is a final extra \r\n.  That means that extra headers can always be added to a request and a response and all web browsers and web servers will still be able to parse the message.

This page allows you to check the HTTP headers and status code of any page.

Note: All requests are made with the HEAD HTTP method for security reasons.
