nginx custom error_page

[kleinchris]

Hello, I wanted to set a custom error_page by setting up:  
if (!-e $request_filename) {
           rewrite ^/de/(.*)$ /de/vbseo.php last;
}
if (!-e means if the requestes file don't exists right?! 

nginx server 0.8.32

Here is my config: http://pastebin.com/2krFJ3sf
