ASP.net - code to display the referrer

Here we go again

[chris_f]

My apologise again. I've not been feeling well and as such seem to have lost the ability to program (or see the bleeding obvious).

Can someone please post the code to bring back the referrer. Every time I try it I get the 'Object reference not set to an instance of an object'.

FYI,
I have tried the following:
1. Referrer = Request.UrlReferrer.AbsolutePath.ToString
2. Referrer = Request.ServerVariables("http_referrer")
3. Referrer = Request.UrlReferrer.ToString()

Can you please include any needed namespaces.

Thanks in advanced

The thing to do in such cases is to get into the Debugger in Visual Studio. In your case, I think you'll find that Request is just a variable. In the case of ASP.NET code, you shouldn't need to define Request, as the code-behind should be inherited from System.Web.UI.Page.

The Page class defines Request and provides it to your page. If you haven't inherited from System.Web.UI.Page, then Request won't be defined.

Thanks Xoc,

System.Web.UI.Page is already inherited in my code. Here's the code if it help. Boy am I owing you guys a few favor's. This is the last problem though, I PROMISE.

Dim Referrer As String

Referrer = Request.UrlReferrer.AbsolutePath.ToString

Response.Write(Referrer)

error message

---

Dim Referrer As String

Referrer = Request.ServerVariables("http_referrer")

Response.Write(Referrer)

Returns a blank page

---

Dim Referrer As String

Referrer = Request.UrlReferrer.ToString()

Response.Write(Referrer)

error message

Thanks again.
Chris.

Any ideas?

Ok. A good night's sleep is all I needed. It's working now.

[big]Xoc, I would like to extend my own personal thanks to you. If you going to the pub conference then I think you deserve two rounds on me :).[/big]
