From: Adam Dickmeiss Date: Fri, 11 Nov 2011 11:17:16 +0000 (+0100) Subject: zoom: allow Torus realm to be set via database args X-Git-Tag: v1.3.14~2 X-Git-Url: http://sru.miketaylor.org.uk/?a=commitdiff_plain;h=298c3c20d481cfce45efa87c69dacdd34861cf05;p=metaproxy-moved-to-github.git zoom: allow Torus realm to be set via database args Database argument realm=x, will subsitute %realm in Torus url with the realm given. If not set, it will use new realm attribute for torus element in configuration.
