Symfony nginx reverse proxy on folder - symfony

Question

I have a simple Symfony application, using Webpack Encore.
I also have a nginx server, with this below configuration to access to my Symfony app:
server {
listen 8080;
server_name localhost;
root D:/Projects/SampleApp/public;
location / {
root D:/Projects/SampleApp/;
try_files /public/$uri /public/$uri /assets/$uri /index.php?$query_string;
}
location ~ \.php$ {
fastcgi_pass php_farm;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
}
}
When I access to http://localhost:8080, my Symfony app works well.
I would like to add another nginx as a reverse proxy, that point http://localhost/SampleApp to http://localhost:8080.
I create this nginx configuration file :
server {
listen 443 ssl http2 default_server;
listen [::]:443 ssl http2 default_server;
ssl_certificate D:/Projects/certificate.crt;
ssl_certificate_key D:/Projects/certificate.key;
server_name localhost;
location /SampleApp/ {
rewrite ^/SampleApp(/.*)$ $1 break;
proxy_pass http://localhost:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_redirect off;
}
}
When I access to http://localhost/SampleApp/login, my Symfony login page works. But :
Assets are not loaded because the base doesn't contains the "SampleApp" prefix (it call http://localhost/assets/app.css instead of http://localhost/SampleApp/assets/app.css)
Links and redirections doesn't works too for the same problem
Do you have any ideas to resolve this problem please ?
Thanks
