Reverse Proxy and bad redirection on several url

Hello,

I work on a website, all was working fine on developpement phase but I have to deploy it behind a reverse proxy. I have a problem on url redirection. It’s hard to describe the problem so I give you several cases when that bug happens :

– When I type https://ip-address/wordpress-home, it works.
– When I type https://ip-address/wordpress-home/, it redirect me on
https://ip-address

– When I type https://ip-address/wordpress-home?page_id=6, it works.
– When I click on the https://ip-address/wordpress-home/?page_id=6 link from the home page, it redirect me on the https://ip-address page again.

– When I type https://ip-address/wordpress-home/repository/, it works.
– When I type https://ip-address/wordpress-home/repository, it redirect me on https://ip-address/repository/.

I tried lots solutions and workarounds that solved similars problems, but no one works (it’s often even worse). I think the problem come from how the PHP deals with url because when I request a specific file, for example https://ip-address/wordpress-home/wp-login.php, it always works.

My configuration :

Apache reverse proxy config file

ProxyRequests On
        ProxyVia On
        <Proxy *>
                Order deny,allow
                Allow from all
        </Proxy>
        ProxyRequests On
        ProxyPreserveHost On
        ProxyPass /wordpress-home balancer://clusterwordpress/
        ProxyPassReverse /test balancer://myclusterapache/

        <Proxy balancer://myclusterapache>
                BalancerMember https://private-ip:80
        </Proxy>
        <Proxy balancer://clusterwordpress>
                BalancerMember https://other-private-ip:80
        </Proxy>

Apache server config file (a test one, almost empty so I know that there are no interferences) :

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/htdocs/wordpress
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/htdocs/wordpress>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Notes :
– None of modications on the wp-config.php or redirection with Apache RewriteEngine already works.
– The siteurl and home value are https://ip-address/wordpress-home both.
I’ve checked them directly in the database with mysql.
– I can’t change the Apache reverse proxy configuartion file because I am not root on this server.

Thank you in advance.

NB : sorry for my bad english.
