msie\_padding is set to on by default (and I didn’t change it). Today I  
added this line to my location php block:  
if ($http\_user\_agent ~ “MSIE 6” ) {  
return 403 “Browser not supported. Please update or change to  
another  
one.”;  
}

So now it is:  
location ~ .php$ {  
try\_files $uri =404;  
fastcgi\_split\_path\_info ^(.+.php)(/.+)$;  
include /etc/nginx/fastcgi.conf;  
fastcgi\_pass unix:/var/run/php5-fpm.sock;  
if ($http\_user\_agent ~ “MSIE 6” ) {  
return 403 “Browser not supported. Please update or change to  
another  
one.”;  
}  
}

It works (with curl and a IE6 user-agent I get my custom error message),  
the problem is that IE6 (real browser) displays its default error page  
(because my message is \< of 512 bytes). But msie\_padding on should “fix”  
that, am I wrong?

If I change the error to something longer it works! For example I set  
one  
(in italian, sorry): “Internet Explorer 6.0 non e’ supportato. Per poter  
visualizzare il sito aggiorna ad una versione successiva o installa un  
browser alternativo (Google Chrome, Mozilla Firefox, Opera …).” and it  
displays my error.

No, nginx adds this padding only to its internal messages.

You create page for MSIE6:  
error\_page 402 = /msie6.html;

and return 402 error:

if ($http\_user\_agent ~ “MSIE 6”) {  
return 402;  
}
