Apache Reverse Proxy Cookie / URL Rewrite

We have a apache reverse proxy setup on an Ubuntu server. The server should redirect users to other server via reverse proxy and store the cookies.

The server with the apache also hosts an Wordpress setup running.

We have set it up, It works fine except there is a flaw in the URL section and cookies.


When we click on the url below https://subdomain.mywebsite.com/?a_aid=137355&brandid=509821&languageCode=EN&mobile=0

It redirects to


And it doesn't store any cookies as far as I can tell.

 <IfModule mod_ssl.c>
    <VirtualHost subdomain.mywebsite.com:443>
        ProxyPreserveHost On
        RequestHeader set Front-End-Https "On"
        ServerName subdomain.mywebsite.com
        SSLProxyEngine on
