Apache does care about slashes at least when it is mapping request
against the filesystem. Specifically, the builtin module mod_dir runs a
handler as last thing in the fixup handler phase and if the URL maps
directory but the URL doesn't have a trailing slash, then the module
will return a redirect response to force the browser to perform the
again but with a trailing slash.
The problem is that Python based frameworks which use mod_python
as merely a jumping off point tend not to perform this trailing slash
redirection in any meaningful way when mapping URLs against any
sort of Python object structures. Even mod_python.publisher, the layer
provided on top of the mod_python core is flawed in this respect.
