I'm looking for a regular expression that will match anything that doesn't contain a backslash. I've been trying regexes out on <http://regex101.com/#PCRE> but neither that not Google is really helping. 

I'd like to match any URL string that looks like it has just one slash in the path:

```
/path/page
/path/anypage

```

And not match any URL with more slashes:

```
/path/morepath/page
/path/morepath/andmorepath/page

```

So far, my regex looks like `\/path\/[a-z]+`, but that happily matches the URLs with more slashes in too. 

How can I exclude these URLs?
