XKCD has an undocumented feature

This URL http://xkcd.com/test/ directs you to the "Undocumented Feature" strip

Just submit a link and let us work it out.

I felt that it might be too easy to miss. I'll repost it.

Still missed it. What's going on here?

Am I missing something?

The URL is xkcd.com/test, this is an undocumented URL. The original strip URL is xkcd.com/1305.

From digging in the js I think that this has something to do with ab-testing for xkcd store.
