System.Web Namespace   HttpRequest Class

---

Gets information about the URL of the client's previous request that linked to the current URL.

[ VB ]
Public ReadOnly Property UrlReferrer As Uri

[ C# ]
public Uri UrlReferrer {get;}

[ C++ ]
public: __property Uri* get_UrlReferrer ( );

[ JScript ]
public function get UrlReferrer ( ) : Uri;

A Uri object.

The following example renders a list of the properties of the URL that referred the client to the current application.

<table width=50% cellspacing=1 class="data" >
<tr>
  <th colspan=2>Referring URL Properties</th></tr>
<tr>
  <td>AbsolutePath</td>
  <td><%= Request.UrlReferrer.AbsolutePath %></td></tr>
<tr>
  <td>AbsoluteUri</td>
  <td><%= Request.UrlReferrer.AbsoluteUri %></td></tr>
<tr>
  <td>Authority</td>
  <td><%= Request.UrlReferrer.Authority %></td></tr>
<tr>
  <td>LocalPath</td>
  <td><%= Request.UrlReferrer.LocalPath %></td></tr>
<tr>
  <td>Port</td>
  <td><%= Request.UrlReferrer.Port %></td></tr>
<tr>
  <td>Scheme</td>
  <td><%= Request.UrlReferrer.Scheme %></td></tr>
<tr>
  <td>UserInfo</td>
  <td><%= Request.UrlReferrer.UserInfo %></td></tr>
</table>

NOTE: UrlReferrer will only work with requests that load in the same or another browser window invoked via a hyperlink. No UrlReferrer object is returned when loading pages into a window using client-side scripting methods. Hence, attempting to retrieve any of the object's property in this case results in an error.
