Help getting regexp to match to set expires headers

Server NGINX
1

Hi there,

I’m trying to get nginx to set expires headers only for assets that have
timestamps at the end of them but am having trouble figuring out exactly
what to put in the conf file. Would anybody be able to help me out?

Here’s what I’ve tried:

Trying to set expires headers for /test.png?1265332681 but not for

/test.png

Works for /test.png?1265332681 but also matches /test.png

location ~* .(htc|ico|css|js|gif|jp?g|png)(?[0-9]+)?$ {
expires max;
break;
}

No expires headers set

location ~* .(ico|css|js|gif|jp?g|png)(?[0-9]+)$ {
expires max;
break;
}

Thanks,
Tim

Location match on path only, without query string, so this won’t
work.

Just a side note: probably you mean “…|jpe?g|…”?

 expires max;
 break;

Another side note: using “break” is pointless here, it just wastes
CPU cycles.

}

No expires headers set

location ~* .(ico|css|js|gif|jp?g|png)(?[0-9]+)$ {
expires max;
break;
}

Try this instead:

location ~* \.(ico|css|js|gif|jpe?g|png)$ {
     if ($args) {
         expires max;
     }
}

Note well: this will work, but you may find it doing strange
things once you add more directives into the above location, see
If is Evil… when used in location context | NGINX for details.

Most generic solution is to use something like this:

location ~* \.(ico|css|js|gif|jpe?g|png)$ {
    error_page 405 = @expiresmax;
    recursive_error_pages on;

    if ($args) {
        return 405;
    }

    ...
}

location @expiresmax {
    expires max;
}
