Hi,

I added a expires as follow:

location ~ ^/images/ {  
root /var/www  
expires max;  
}

if I do a curl -I [http://localhost/images/sample.jpg](http://localhost/images/sample.jpg), I got following  
headers, but can not find the “Expires” in the headers, what I did wrong  
here? Thanks.

What other “location” lines do you have for this server? Only one of  
them will be used for the request /images/sample.jpg.

there is another one, but more specific, but it comes before location ~  
^/images/:

location ~ “^(/images/)(\d{1})/(\d{2})/(.\*.jpg$)” {  
}

There is no such thing as “more specific” when you are talking  
about regular expressions. First match wins. See here for  
details:

If the only two “location” blocks in your server are:

location ~ “^(/images/)(\d{1})/(\d{2})/(.\*.jpg$)” {  
location ~ ^/images/ {

then the request for /images/sample.jpg will be handled in the second  
one.

Which is not what you reported seeing.

You are right, thanks to Francis too for giving me the right direction  
to  
look for the problem, it’s really the other location that should have  
the  
expires set as well, thanks.
