[tor-commits] [onionoo/master] Add two new parameters "as" and "flag".
commit ef51f1b4d6a44699177c2c09d19bfa8e6c2bac9e
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date: Tue Apr 9 05:32:19 2013 +0200
Add two new parameters "as" and "flag".
Also fix a potential bug in the servlet's filtering and sorting code.
It's unclear whether this really was a bug, but let's clean up the code
just in case.
