Is there a difference between these URLs in regards to having slashes at the end of the URL?

They are handled as different requests, although they might match the same resource/handler/routine at the end and be processed in the same way.
As the one with / is supposed to be something similar to a directory, all relative links will be inside the / i.e. previous/target/something ... while the one without will have the relative links be at the same level previous/something.
