Check your server result codes / show HTTP server headers

This tool will check your server headers and the HTTP result codes it returns. It will follow any redirects it finds along the way, whenever possible. With this tool you can check to see how your server is redirecting and if your server is returning 404 for URLs which do not exist.

This tool identifies itself with the following user-agent (this might be logged on the server):

oyoy.eu Server Header Checker, User IP: 38.107.191.81 (http://oyoy.eu/)

Please enter the full URL for the page you want to check. The URL must begin with HTTP (secure sites cannot be tested at the moment). Example: http://www.cnn.com/

URL to check:
  Show all server header fields

A short summary of the result codes:

• 200 OK
  This means that your server was able to return content for the URL you requested.
• 301 Moved Permanently
  The URL you requested has moved permanently, all further queries shoud be directed to the new location. If an old page is no longer valid and you have a new one in it's place, you should use 301-redirects whenever possible. The search engines will then replace the old URL with the new one and transfer any possible "value" of the old URL to the new one.
• 302 Found
  The server has found a temporary redirection. Since this is temporary, this URL should be used once again for the next time (not the new URL).
• 304 Not Modified
  You shouldn't be seeing this here - it only returns 304 when the client asks for a newer version of a URL.
• 307 Temporary Redirect
  This is similar to a 302 redirect, the redirection is temporary and the existing URL should continue to be used.
• 400 Bad Request
  The server didn't understand what you were looking for.
• 401 Unauthorized
  The server does not want to give you access to this content without authentification.
• 403 Forbidden
  The server does not want to help you. period. Authentification will not help in this case.
• 404 Not Found
  Oops, the file you were looking for is not found. Search engines need a 404 in order to know which URLs are valid and which are not. In order to keep any value of the old URLs, you should keep a dummy page at the location of the old URL and 301-redirect from there to the new URL (assuming you have a new one).

• 410 Gone
  The URl you were looking for is... gone. This is similar to 404.
• 500 Internal Server Error
  Your server is melting - something is wrong, it's not answering to your requests properly. Contact your System-Administrator or Web-Hoster!
• 501 Not Implemented
