Should we always add the final / or avoid it ?


  1. /url-without-trailing-slash
  2. /url-with-a-trailing-slash/

Does it make a difference?

No difference between them. (As opposed to not putting a slash on links into a directory, for example.) I don't think I've ever seen anything saying that you should or shouldn't, though being consistent in your own behavior is generally not a bad idea, either.

One of the most wasteful redirects happens frequently and web developers are generally not aware of it. It occurs when a trailing slash (/) is missing from a URL that should otherwise have one. For example, going to "http://astrology.yahoo.com/astrology" results in a 301 response containing a redirect to "http://astrology.yahoo.com/astrology/" (notice the added trailing slash). This is fixed in Apache by using Alias or mod_rewrite, or the DirectorySlash directive if you're using Apache handlers.

But this does not apply to the question example –  leonbloy Oct 3 '11 at 2:25

The other answers have identified that it doesn't seem to technically matter.

For me it is a matter of perception, if there is a trailing slash I'd expect something to be following it, a file name, an anchor.

I also think a lack of a trailing slash looks cleaner.

It's a matter of Apache configuration (can't say about others)

Some Apaches can't handle site/path as site/path/index.file

Semantically both URL declare the same resource

It's nothing whatsoever to do with Apache. It's a browser issue. –  DisgruntledGoat Oct 3 '11 at 14:30
@disgruntledgoat- Wrong statement! The DirectorySlash directive determines whether mod_dir should fixup URLs pointing to a directory or not. Typically if a user requests a resource without a trailing slash, which points to a directory, mod_dir redirects him to the same resource, but with trailing slash for some good reasons... –  Lazy Badger Oct 3 '11 at 14:38
the question is not about directories, it's about the root domain. –  DisgruntledGoat Oct 3 '11 at 15:01
Apache is not the only webserver –  slow diver Jan 25 '12 at 18:47
