Case sensitive Channel urls problem
It's not just Windows / Linux / OSX that have different file system case sensitivities, but even different distributions of Linux can have them.  Or the same distribution, but with different file systems.  Or the same distribution and same file system, but one has been configured to be case sensitive and the case insensitive.

Instead of accounting for all of the different possibilities for a given route (example.com/articles, example.com/Articles, example.com/aRticles, example.com/ArTiClEs), it's going to be much less of a headache to just force lowercase at the web server level.
