- IMPORTANT: There is a risk that this variable could be misused for cross-site scripting (XSS).
- URL parameters passed into HTML form fields must be entity ENCODEd.
  Example: <input type="text" name="address" value="%URLPARAM{ "address" encode="entity" }%" />

- Double quotes in URL parameters must be escaped when passed into other TWiki variables.
  Example: %SEARCH{ "%URLPARAM{ "search" encode="quotes" }%" noheader="on" }%
- When used in a template topic, this variable will be expanded when the template is used to create a new topic. See TWikiTemplates#TemplateTopicsVars for details.
- 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.
