How Can I Reliably Access the HTTP Referrer in ASP.NET?

Accessing the HTTP Referrer in ASP.NET

Capturing the HTTP Referrer in ASP.NET serves as a valuable method for tracking browser history and gaining insights into where users are coming from. Despite the occasional unreliability of the HTTP Referrer, it's crucial to have a reliable mechanism for retrieving it when present.

Solution

To obtain the HTTP Referrer efficiently and reliably in ASP.NET, leverage the UrlReferrer property of the current request:

Request.UrlReferrer

This property examines the Referer HTTP header within the request, which is subject to optional inclusion by the client (user agent). If supplied, the UrlReferrer property provides access to the referrer information, enabling you to analyze user behavior and enhance the user experience on your web application.
