Apache rewrite rules behind a nginx proxy

Question

I am running nginx (:80) in front of an Apache webserver (:8080)

Nginx config (snippet):

location / {
    proxy_pass        http://www.domain.tld:8080;
    proxy_set_header  X-Real-IP  $remote_addr;

If I set localhost instead of www.domain.tld, my browser gets redirected to http://localhost:8080.

Apache rewrite rules:

RewriteEngine On
Options +FollowSymlinks
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !\..+$
RewriteCond %{REQUEST_URI} !/$
RewriteRule (.*) http://%{HTTP_HOST}/$1/ [L,R=301]

RewriteCond %{REQUEST_URI} !v2/
RewriteRule ^(.*)$ v1/$1 [L]

So far, so good.

However, every link (which uses relative paths) appears as http://www.domain.tld:8080/page instead of staying on port 80.

Is there any way to solve this through the rewrite rules? I don't want to use absolute paths.

Thanks

Solved by adding this to the nginx config:

proxy_set_header Host $host; 
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
