You have to use redirects when the file name, slug, or path of an article has been changed for some reason.

To handle this scenario use theprevious_url property.

---title: Overviewpage_title: Getting Started Overview | RadSplitter for ASP.NET AJAX Documentationdescription: Overviewslug: splitter/getting-started/overviewprevious_url: controls/splitter/getting-started/getting-starter-overviewtags: overviewpublished: Trueposition: 0---

Note that comma characters inprevious_url are considered incorrect and are not supported. If you need to redirect a comma-containingprevious_url value, either leave the article without a redirect or build and commit a rule directly in theweb.config file.

As shown inExample 1, the path set to theprevious_url property has to exclude only thehost andbase url of the URL. Therefore, if the old URL is:

http://host/devtools/aspnet-ajax/controls/splitter/getting-started/getting-starter-overview

the value to be used will be:

/controls/splitter/getting-started/getting-starter-overview

Note that multiple redirects are not supported. This means that:

• A single article can be redirected to a single article, not to many, that is, a givenprevious_url value can be present on only one file.

• Several articles cannot be redirected to a single article. If you need such a rule, build and commit one in theweb.config file. Most likely, you will be able to handle an entire folder redirect with a single rule.
