Setting a variable set with the URL protocol

Variables can be set in an internet browser window, by specifying the url:

http://<host name>/<virtual folder name>/
<info page name>.asp?$Action{name=setValue}
{DataSourceName=<VariableSetDataSource name>}
{DataSourceItem=<Variable name>}
{Value=<value>}

This way, you can set a variable when opening an info page.
