Smart URL's
When writing an error document or error page use Folders and not direct url's. Why? Because you may wont to change your programming styles or add a script to process the error documents at some point, this way you can change the file name without adding processing time to the servers CPU and ram, speeding up the page to client process.

.htaccess File Sample.
Below we have placed an example of the .htaccess file, you can highlight the code and paste it inside a text file (error.txt) upload it using FTP (file transfer protocol) and rename the file error.txt --> .htaccess the server will process the request and rename the file for you. If you dont know how to transfer it to .htaccess, we can provide you with a downloadable .htaccess for you to use via email, just open it in a text file editor like Notepad and change the URL after the corresponding error number, ensure their is one space after the corresponding error number and no space after the URL. Each error document must be placed on a new line, otherwise it will make your whole website stop working. If you got an error email us for free advise. Your current host may not support .htaccess files.

ErrorDocument 400 /error_document/400/
ErrorDocument 401 /error_document/401/
ErrorDocument 403 /error_document/403/
ErrorDocument 404 /error_document/404/
ErrorDocument 408 /error_document/408/
ErrorDocument 500 /error_document/500/

Later on in our tutorials we will look at Mod Re-write and redirection using .htaccess for telling the user-agent the webpage still exsist's but has moved to another location, also search engines will know your pages are not lost forever but moved to a new position with in the directory, pickup the new page and rank it as requested.
