Server behavior6.4

No404 page

YesCompression

  • This website does not return a 404 error HTTP status code for missing pages. This is bad because search engines like Google might mistake this for a real page of content.
  • This website was served with GZIP encoding. This is very good because it reduces the loading time of a web page.
