Tim Berner Lee argued in his article “Cool URLs don´t change” to set always a server redirect if you have moved a page.
The frequently seen page reload using the header tags <META HTTP-EQUIV=REFRESH CONTENT="0;URL=http://new.server.de/tips_tricks/"> is only suboptimal as spider will not follow them. Put instead one of the following lines in your your Apache con/http.conf or into the .htaccess file of your directory.
.htaccess
|wj_htaccess.txt|
Preventing bots from increasing your server load is another suggestion.
