View Website Headers
About Website Header Viewer
This tool allows you to view server headers for any page on a website. Viewing server headers allows one to identify not only information that is being sent by the server to the client but also the ability to find vulneribilities in their infrastureure.
Headers Description
HTTP headers let the client and the server pass additional information with an HTTP request or response. An HTTP header consists of its case-insensitive name followed by a colon (:), then by its value. Whitespace before the value is ignored.
