Server configuration

HTTP redirects
(Critically important)
This page redirects to "https://911memorial.org/"
HTTP header
(Important)
The web server version is sent within the HTTP header.
No X-Powered HTTP header is sent.
The web server transmits the web page (HTML) in compressed form.
Performance
(Somewhat important)
The page response time of 0.63 seconds is longer than the recommended limit of 0.4 seconds. A high response time unnecessarily slows down search engine crawling and results in bad user experience as well.
This page loads 26 JavaScript files. This may affect the load time negatively.
This page only loads 3 CSS files. That's ok.
The file size of the HTML document is fine (76 kB).
