Change default URL format for content items
For each built-in or dynamic module, Sitefinity CMS applies default URL format. You can change the default format for modules with single content type, multiple, or hierarchical content type by using custom implementation of URL formation.
You do this by changing the format in which the system generates URLs of content items. For example, the default format for generating the URLs of events is YYYY/MM/DD/EventTitle. However, if you want to publish on the same date several events with the same title, this will cause URL conflict. You can overcome this by changing the way the URL is generated.
