Rewrite Rules and Expires-Header with Apache/nginx

Question

I come today with a problem of browser caching static files.

I have a Prestashop Website on a Plesk server running with Apache and Nginx.

Prestashop generates a .htaccess file with apache rewrite url rules :

RewriteRule ^([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$1$2$3.jpg [L]
RewriteRule ^([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$1$2$3$4.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$1$2$3$4$5.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$4/$1$2$3$4$5$6.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$4/$5/$1$2$3$4$5$6$7.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$4/$5/$6/$1$2$3$4$5$6$7$8.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$4/$5/$6/$7/$1$2$3$4$5$6$7$8$9.jpg [L]
RewriteRule ^([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$2/$3/$4/$5/$6/$7/$8/$1$2$3$4$5$6$7$8$9$10.jpg [L]

And Nginx was set up to add expires-header to static files :

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
    expires 30d;
    add_header Pragma public;
    add_header Cache-Control "public";
    try_files $uri @fallback;
}

This will works for static files that their urls were not rewrote by Apache :

url example : http://www.domain.tld/modules/homeslider/images/image_name.jpg

Server: nginx
Date: Sun, 20 Nov 2016 19:32:33 GMT
Content-Type: image/jpeg
Content-Length: 50616
Last-Modified: Thu, 17 Nov 2016 14:47:22 GMT
Connection: keep-alive
ETag: "582dc2fa-c5b8"
Expires: Tue, 20 Dec 2016 19:32:33 GMT
Cache-Control: max-age=2592000
Pragma: public
Cache-Control: “public”
Accept-Ranges: bytes

But Not for product's images that their urls were rewrote by the apache rules :

url example : http://www.domain.tld/156-home_default/image_name.jpg

Server: nginx
Date: Sun, 20 Nov 2016 19:34:11 GMT
Content-Type: image/jpeg
Content-Length: 7587
Connection: keep-alive
Last-Modified: Thu, 17 Nov 2016 21:14:27 GMT
Accept-Ranges: bytes
X-Powered-By: PleskLin

The question is : How to make the nginx expires-header apply to files urls rewrote by the Apache Rewrite rules ?

Thanks in advance.

EDIT

The server management is handle by Plesk 12.5.

nGinx is used to handle static files. I don't know much about its configuration.

In Plesk domain.tld -> Nginx configuration, I checked "Smart static files processing" and "Serve static files directly by Nginx". And in "Additional Nginx directives", I added the expires-header code. That's all modification I have done on this. It's as default plesk configuration.

Can you provide some more context, like full sample URL and more nginx configuration? Also, I guess that nginx is routing requests with Apache being an upstream? — Jan Papenbrock, Nov 20 '16 at 20:26
both example above have the "Server: nginx" reply, so those are being served by nginx. What you need is to put your location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { earlier in your nginx config file, because order matters. — peixotorms, Nov 21 '16 at 02:11
I added the nginx configuration file in a new edit. The use of `PT` flag in the apache rewrite rules did not help. Also, as you see, I can't modify the order of the nginx rules because it's an auto-generated file. — JazZ, Nov 21 '16 at 06:31
When you cannot change nginx configuration, you could add the appropriate cache rules to `.htaccess` instead. Would that be possible, can you edit `.htaccess`? — Jan Papenbrock, Nov 21 '16 at 10:34
@JanPapenbrock Yes I can. That was the first try. The rules are already in the file but not applied... I think because of nGinx who handles Static files. I'm kind of stuck with this... — JazZ, Nov 21 '16 at 14:04

I figured out how to solve this. Not a big mystery...

I did convert the rewrite rules from apache to nginx and ignore the .htaccess.

That did the trick.

The new "Additional nginx directives" :

# Deny all for hidden files/directory (.htaccess, .htpasswd, etc...)
location ~ /\. {
    deny all;
    access_log off;
    log_not_found off;
}

rewrite ^/api/?(.*)$ /webservice/dispatcher.php?url=$1 last;
