I'm not sure I completely understand this, would this always add a / to the end of the URL or only during certain conditions? I would think that you'd want to add / but only when with the following conditions:

• The url does not end with a file extension
• The url does not end with a /

Special considerations:

• Make sure to ignore domain names (i.e. a request sent to w3develops.org should not be considered a file extension)
• Make sure that dots(.) aren't going to be in any part of the api (such as a restful API) so if you have something like a get w3develops.org/users/some.user.with.a.dot but I think api calls wouldn't care whether or not there would be a trailing /.

I'm guessing this addresses all of this already but I'm not sure how these rules work exactly: what conditions are associated with which rules and such--are additional conditions applied to all the rules you have in the file? Are the conditions met when any one of the conditions are true (I'm guessing so--I don't think they could all be true).

I'm closing this as an unnecessary patch. @waterlgndx thank you for your input!
