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

Do web frameworks and web servers (e.g. Apache, Nginx, Django) handle these requests differently?
In Django URLs without forward slashes automatically have a forward slash appended to them. This is a preference of the Django developers and not a hard-coded rule of the web (I think it's actually a setting in Django).
The browser will treat them differently when it comes to relative URLs. A page at:
http://server/path
with a relative link like:
<a href='other'>
will resolve that link to:
http://server/other
replacing path with other. Whereas if the starting URL was:
http://server/path/
then the resolved link would be:
http://server/path/other
If path is a directory rather than a file, most web servers will automatically redirect from:
http://server/path
to:
http://server/path/
because that's almost certainly what you meant.
/ is the separation character.
From the RFC
Some URL schemes (such as the ftp, http, and file schemes) contain names that can be considered hierarchical; the components of the hierarchy are separated by "/".
Having a / at the end states that there might be more stuff in 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.
Just a side note that search engines view these as 2 different pages. Thus hurting your seo.
