Little surprises in HTTP Headers

Last week I move a blog I’ve got in Spanish to wordpress.com. Basically I really like wordpress.com and I believe it’s really worth it in terms of freeing my time from administering a wordpress installation and keeping up with the security fixes etc. And today, having a little bit of time I was tweaking my old website to redirect to the new site using an HTTP permanent redirect header. This is what I found in the HTTP headers:

[golan@mars ~] % HEAD http://roncero.org/blog/
200 OK
Cache-Control: max-age=260, must-revalidate
Connection: close
Date: Thu, 15 Oct 2009 21:35:09 GMT
Server: nginx
Vary: Cookie
Content-Type: text/html; charset=UTF-8
Last-Modified: Thu, 15 Oct 2009 21:34:29 +0000
Client-Date: Thu, 15 Oct 2009 21:35:09 GMT
Client-Peer: 76.74.254.123:80
Client-Response-Num: 1
Link: ; rel=shortlink
X-Hacker: If you're reading this, you should visit automattic.com/jobs and apply to join the fun, mention this header.
X-Nananana: Batcache
X-Pingback: http://blog.roncero.org/xmlrpc.php

So, apart from various bits of information (nginx), what I really really liked was the X-Hacker header :-). Fancy a job?
