I have a controller/action that creates content in the Umbraco content tree with the same path as the controller/action, but when it redirects to that content it recursively calls the action again and get stuck in an infinite loop?

Situation:

• Consider a controller named DocumentType with an action named Index that takes a parameter named Id
• The controller responds to the route /DocumentType/Index/1234
• I have created documents in the content tree mimicing the controller's route: /DocumentType/Index/1234
• The routing should navigate to the document, if it exists, otherwise it should go to the action on the controller.
• The action is responsible for creating new content at the requested path and then redirect to that content
• The redirection is recursively calling the action on the controller instead of serving up the content that was just created

Success:

1. Manually create content /DocumentType/Index/5678 in content tree
2. User navigates to http://website.com/DocumentType/Index/5678
3. Umbraco returns content with correct template

Fails:

1. User navigates to http://website.com/DocumentType/Index/1234
2. Content does not exist, so routed to Controller: DocumentType, Action: Index, Id: 1234
3. Action creates new content at /DocumentType/Index/1234 and remembers HiveId of new item
4. Action redirects to content of new HiveId
5. *** Action /DocumentType/Index/1234 is called again, NOT the content in Umbraco ***

How do I tell Umbraco to serve up the newly created content rather than redirecting me back to Controller/Action?

Environment:

• Umbraco Version: 5.1
• Asp.Net Version: 4.0
• Windows and IIS Version: Windows 7 and IIS Express 7.5
