I’m looking to white list all of the pages under a subdirectory but no pages underneath that.

I am attempting to use the following regex match as a whitelist rule with a negative lookahead:

`/page/.+/(?!.+)`

Basically I want to get all the pages under page, but none of the pages that may exist under any of those pages. Is this regex possible? I believe I could do a blacklist for those items but saw that would make indexing slower and while that’s not a deal breaker I was hoping I could just create a clear whitelist rule that would perform the same function.

Could you just match any character after /page/ except another slash?  
[^/]+
