Please stop saying backslash
Unless you're coding or involved in some very niche subject that I'm not aware of, you'll never need to use a \ or even need to know that word. They almost never appear in URLs. Certain browsers will correct this mistake, but just stop, seriously.
Why do so many on-hold recording messages, like for certain VA hospitals even, egregiously use the word backslash as though it means the same thing as slash? Not only are you showing your computer illiteracy, but you're wasting your time and breath saying a syllable YOU'LL NEVER NEED.
To recap, / is a slash, the only one you'll ever need, so cut it out.
