The current "stat pages" interface allows ATS to return custom content for special URLs.

It is some problems:

1) the syntax is {cache}{cache}/" class="external-link" rel="nofollow">http://

{cache}{cache}
/ which doesn't work with current browsers requiring
a remap. We could use something like http://cache.ui.trafficserver.apache.org instead.

2) Many of the pages are broken or have less than useful functionality.

3) the security model could use some work.
