Okay... I'm not exactly sure if what I'm trying to do is possible...
Lets say I have a website at:
website.com/dir/
Then I also have a sub directory at:
website.com/dir/portal/
What I want to do... if someone goes to /dir/, I want them to get forwarded to /dir/portal/
Then if someone goes to /dir/forum/, I want them forwarded to /dir/
So the route would be:
/dir/ => /dir/portal/
/dir/forum/ => /dir/
This is my current htaccess...
