I have URLs in the following format:

```
STATIC_PATH=http://abc.com/0123/3456
STATIC_PATH=http://xyz.com

```

I want to match until and including the first forward slash not immediately followed by a forward slash. In the first URL that would match be `http://abc.com/`, in the second URL, it would be `http://xyz.com`. Can you give me the regex for it? Thank you.
