This tool will show you received http headers on requested host at requested port (default is 80). Headers show information that your browser would receive but it would not display it. For instance, "Set-Cookie:" asks your browser to create a local cookie, "Last-Modified:" tells when the page or file was most recently modified, "Location:" asks your browser to go to another URL, where the document you requested is really located. You will also obtain status code, a number which indicates the status where 200 is OK.
