Hello everyone ,  
First of all , I would like to thanks Igor and his team for this real  
nice web server which can take a huge of work in less resources and fast  
speed .

I hope to get the answers for my questions as i need this answers to  
complete my work .

My questions:-  
1.How i can set a 404 image instead of page , what i means if for  
example some one goes for un-exist image url  
([http://www.example.com/flk123j12l31.gif](http://www.example.com/flk123j12l31.gif)) so how i tell nginx to  
redirect him to ([http://www.example.com/notfound.jpg](http://www.example.com/notfound.jpg)) , i try to use  
this rules , I try to use this rules but it not help .

location ~ /(upload/Pictures|upx/uploads)/.\* {

valid\_referers none block server\_names ~([example.com|google|lll1.com](http://example.com%7Cgoogle%7Clll1.com));  
if ($invalid\_referer) {  
error\_page 404 = /notfound.gif;  
rewrite ^(.\*)$ /leech.gif break;  
}  
}

2.How i can put multiple files in if statement .

What i have now

if ($request\_filename ~ “showthread.php$” ) {  
rewrite ^/vb/(._)$ /vb/vbseo.php last;  
}  
if ($request\_filename ~ “external.php$” ) {  
rewrite ^/vb/(._)$ /vb/vbseo.php last;  
}

if ($request\_filename ~ “archive/index.php$” ) {  
rewrite ^/vb/(.\*)$ /vb/vbseo.php last;  
}

What i would like to have and works

if ($request\_filename ~ (archive/index|external|showthread).php$) {  
rewrite ^/vb/(.\*)$ /vb/vbseo.php last;  
}

4.Does it give a performance boost when i set workers equals to cores  
numbers?

5.What your advices about my images server nginx file.

Ad.1 - Use try\_files

Ad.2 - Don’t use if, instead use different location to capture and  
rewrite

location ~ ^/vb/showthread.php$ {  
rewrite ^/vb/(.\*)$ /vb/vbseo.php last;  
}

Ad. 4 - Yes, also you should use worker\_cpu\_affinity im multicore  
server, read wiki and google it for more information.

Ad. 5 - I Don’t feel to conifdent to check your config ^\_^.
