Should I use underscores or hyphens in URLs?
Solution:
It does make a difference; it would be better to go with dashes or hyphens if you can. If you have underscores and if things are working fine for you don’t worry about changing your architecture. But for the time being dashes or hyphens are treated as separators and underscores are not. That might change in the future but that’s the way it stands right now.
