URL Parameters are parameters whose values are set dynamically in a page’s URL, and can be accessed by its template and its data sources. This makes pages incredibly dynamic, enabling a single page to power an endless number of views.
The URL points to a web page. The URL may contain a static path, such as:
http://www.myStore/womens/Clothing.jsp
As is the case with any URL, you can append dynamic parameters that are used by the page located by the URL to the URL itself. At runtime, those dynamic parameters are replaced by property values, then passed to the page. For example:
http://www.myStore/womens/Clothing.jsp?type=$itemType&name=$displayName
The type parameter is replaced with the item’s item type and the name parameter is replaced by the item’s display name.
