Enum ApplicationUrlDetection

Specifies how the application main URL is detected from incoming HTTP requests.

Namespace: Umbraco.Cms.Core.Configuration.Models
Assembly: Umbraco.Core.dll
Syntax
public enum ApplicationUrlDetection

Fields

Name Description
EveryRequest

The URL is updated from every new incoming HTTP request (legacy behavior). This is vulnerable to host header poisoning.
FirstRequest

The URL is set from the first HTTP request and then locked. Subsequent requests with different host headers are ignored.
None

No auto-detection. The application URL must be explicitly configured via UmbracoApplicationUrl. Operations that require a URL (invitations, password resets) will fail if no explicit URL is configured.
