HTTP redirects

(Critically important)

This page redirects to "https://www.arc.ed.tum.de/arc/startseite/"

WWW Redirect

HTTP header

(Important)

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 0.97 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 5 CSS files. This may affect the page load time negatively.

This page only loads 2 JavaScript files. That's good!

The file size of the HTML document is fine (81 kB).
