Secret pages in API reference links

[Gimmick]

So just recently while browsing the Newgrounds API reference, on the topic of SaveFiles, I clicked on the SaveGroup hyperlink inside the code snippet and it takes me to this page which asks for a username and password instead of this. It happens for other NG API links as well, for example clicking on the "SaveFile" on the same page leads to a similar domain url.

The code snippets in question are:

public static var currentFile:SaveFile;

Clicking on the highlighted "SaveFile" takes me to the previously mentioned page.

public var group:SaveGroup;

Clicking on the highlighted "SaveGroup" takes me to the aforementioned page. (staging2.newgrounds.com/.../)

Furthermore, SaveGroup, SaveRating and SaveKey are not accessible either - they all redirect to SaveQuery. Is this intentional?

I'm pretty sure the urls with "staging.newgrounds" is where staff test things before going live. I imagine new apis are tested there first to make sure they don't wreck the site
