2013.12.22     Version 4.10 released, service disabled
Service is disabled for non onion urls. .onion urls do still work.
Because I simply don't have time to maintain this
project. Deal with potential abuse etc. Otherwise I have been very
happy with Google App Engine and it's reliability and performance.
It was good as long as it lasted. - Thank you.

Added second primary web-DNS service server. It's hosted on
another of my virtual servers, using uWSGI and Nginx.

server resources, because if JS is not evaluated from create
page database won't be accessed at all.

redirect but with no-cache tag. It's quite pointless afaik.
Now it's fixed. Frontpage is browser cacheable and there is
no additional redirect anymore.
