- Also supports
topic_version
and attachment_version
parameters. These can be used with advanced store implementations to select specific attachment versions. However simple file-based stores do not normally support them. The 'old' way of building URLs using
PUBURL
involved concatenating the web and topic names to the
PUBURL
e.g.
%PUBURL%/Main/SystemFeatures
. This practice is
strongly discouraged, as it does not correctly handle encoding of the parts of the URL. At the first opportunity you should replace all such URLs with the equivalent
%PUBURL%{topic="System.MainFeatures"}%
, which will handle URL encoding for you.
ATTACHURL provides a shorter way to refer to the attachments on the current topic.
