- Watch out for TWiki internal parameters, such as
rev, skin, template, topic, web; they have a special meaning in TWiki. Common parameters and view script specific parameters are documented at TWikiScripts.
- If you have
%URLPARAM{ in the value of a URL parameter, it will be modified to %<nop>URLPARAM{. This is to prevent an infinite loop during expansion.
