I've this link and as you can tell there's an additional / in the finish. Essentially i've got a restaurant_pos folder by having an index.php file inside it but apache is adding the additional slash. I figured there is a method to do that in htaccess with directory directives off or something like that like this...unsure the title...any ideas

This will get the job done for you personally (redirect if UR has trailing slash):

DirectorySlash Off

RewriteEngine On
RewriteBase /

# get rid of trailing slash
RewriteRule ^(.*)/$ $1 [R=301,L]

But you might have that extra slash added by another rule inside your .htaccess. If above won't help and you've got some rewrite rules already in position -- please publish them inside your question.
