"X-Coral-Control: redirect-home headers show up. This header is used to tell Coral that if Coral can’t handle the load of requests for cached copies of your page, it should redirect these requests back to your site." This presumably makes sense if the site operator is prepared to scale or has a scaling strategy to put into play - but it might take some time. He'd rather have people bounced back to his infrastructure in order to see how to optimize than loose the visibility by coral. Also - (just a guess) some of the other headers - like the limerick - could be there to get around that IE behaviour where it won't show the real HTTP error message and instead shows you something generic and useless.
