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

Retrieving the HTTP Referrer in ASP.NET

When developing web applications in ASP.NET, it can be useful to access the HTTP Referrer header to gain insight into the previous URL visited by a user before navigating to your site. This header may provide valuable information for analytics, user flow analysis, and other purposes.

To reliably retrieve the HTTP Referrer in ASP.NET (C#), utilize the UrlReferrer property of the current request:

Request.UrlReferrer

This property will parse the Referer HTTP header from the request, which contains the URL of the previous page. However, it's important to note that this header is optional and may not always be present or reliable, as it can be modified or removed by user agents or proxy servers.

By using the UrlReferrer property, you can retrieve the HTTP Referrer if it exists, providing a convenient and straightforward approach to access this information in your ASP.NET application.
