HI all… I have implemented nginx as a front end proxy for my ISPconfig  
3 apache based web server. Works quite nice but I have one issue. I have  
some png files that are recreated every few minutes.

I am using the expires option on static files so I want to exempt these  
png files but not all png files.

If I understand correctly, this is done with another location directive,  
something like below

location /weather/graphics/\*.png {  
expires off  
root /var/www/VIRTUAL1.com/web/;  
access\_log /var/log/ispconfig/httpd/VIRTUAL1.com/access.log;

Question is where do I put this?

Thanks for your help…

Rob

My vhost conf file is below. host name has been changed…

server {

# listen 80;

server\_name [www.VIRTUAL1.com](http://www.VIRTUAL1.com) [VIRTUAL1.com](http://VIRTUAL1.com);  
#default proxy settings shared are among all virtual hosts  
access\_log off;  
include /etc/nginx/proxy.conf;  
location ~\*  
^.+.(jpe?g|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|html?|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3)$  
{  
#forcing browser to cache locally static content for 1 day  
expires 1d;  
root /var/www/VIRTUAL1.com/web/;  
access\_log  
/var/log/ispconfig/httpd/VIRTUAL1.com/access.log;  
#graceful fallback in case if static content doesn’t exist  
\<------\> include /etc/nginx/proxy\_fallback.conf;  
}  
}
