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):

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 If an old page is no longer valid and you have a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.
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.

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). [
