Using the "umbracoUrlAlias" alias with a textstring property will enable you to provide multiple URLs for a content node.
For example if we were to enter "warrenbuckley,test/this-is-a-test", this would resolve the following URLs to the same page.
- /warrenbuckley.aspx
- /test/this-is-a-test.aspx
Please note that the values you use must be lowercase, not use a leading slash and not use a trailing ".aspx".
