Use of HTTP_REFERER in Global.asa

[Prabhat]

Hello,

I have the below requirement.

When ever my website is opened by any link: say clicked from the google
search result or a link from other website:

Then I should able to know the referrer URL. How Do I get that?

I know about Request.ServerV ariables("HTTP_ REFERER"). So I used this in
"global.asa " file in "Session_OnStar t" event like this:

Sub Session_OnStart
Session("Referr alURL") = Request.ServerV ariables("HTTP_ REFERER")
End Sub

Sub Session_OnEnd
Session("Referr alURL") = ""
End Sub

So that I can use the session variable any where in my website, because the
HTTP_REFERER will give the URL of the last webpage.

But this seems to not working.

Please help.

Thanks
Prabhat

HTTP_REFERER is not always available (see http://www.aspfaq.com/2169). This
is, however, not one of those cases. This technique worked fine for me, as
long as the click actualy started a new session. I just did this on my own
box, with an HTML file I called from http://localhost/file.htm, with a link
to http://my_machine_name/file.asp, where global.asa in the root set a
session variable just like you do below, and file.asp outputs the session
variable. Worked flawlessly, as long as I started from scratch (e.g. closed
the browser).

If you are on your site, and then go to Google, and click on a link that
takes you to your site, session_onstart () won't fire because you still have
the old session.

Don't try to set the string to an empty string in session_onEnd. There is
no point. If session_onEnd is actually being called, then your variables
are blown away for you. But more often than not, it will not be called
(see http://www.aspfaq.com/2078).

My guess is that session variables are not working
(http://www.aspfaq.com/2157) or global.asa is not being called at all (see
http://www.aspfaq.com/2076). To isolate the problem, create a global.asa
that sets a session variable (just a constant/string, not based on
servervariables ) in session_onstart . Open a new browser window, navigate to
a page that sets a different session variable, then navigate to a third page
that displays them both.

Then I should able to know the referrer URL. How Do I get that?

I know about Request.ServerV ariables("HTTP_ REFERER"). So I used this in
"global.asa " file in "Session_OnStar t" event like this:

Sub Session_OnStart
Session("Referr alURL") = Request.ServerV ariables("HTTP_ REFERER")
End Sub

Thank you, Dave.

I thought I had heard otherwise, but clearly I am wrong.

What do you think could be Prabhat's problem then?

Probably a lack of understanding of either (a) when a session starts, or (b)
when the HTTP_REFERER header is sent.

Aaron was probably right on when he suggested global.asa was not firing at
all. This would be true if the OP failed to set up the folder as an
Application, and would fall under (a) above.
