Adding a trailing slash on one condition in apache mod_rewrite - apache

Question

I know this is a common problem and I know there is a simple solution, however I cannot get the solutions that I have found online to work with my situation.
I have an address as such:
https://localhost/cms
However, when a visitor goes to this address apache cannot find the resource, but if a visitor goes to:
https://localhost/cms/
it works, as expected. So, to combat this I am trying to created a mod rewrite condition, but I am having a bit of trouble. Here is my conf file so far:
<VirtualHost *:443>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(.*)/cms
RewriteRule ^(.*)$ https://%{SERVER_NAME}/$1/ [L,R=301]
ProxyPreserveHost on
ProxyRequests off
ProxyPass /cms/ http://localhost:9000/cms/
ProxyPassReverse /cms/ http://localhost:9000/cms/
</VirtualHost>
Any suggestions?

Answer 1

So, I figured it out by using ReverseProxy, here is the updated conf file:
<VirtualHost *:443>
ProxyPreserveHost on
ProxyRequests off
ProxyPass /cms/ http://localhost:9000/cms/
ProxyPassReverse /cms/ http://localhost:9000/cms/
ProxyPass /cms http://localhost:9000/cms/
ProxyPassReverse /cms http://localhost:9000/cms/
</VirtualHost>
