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

No, in your case it would [but doesn't] give only the URL of referral
site when opening the session.

Better put this file as an include
<!--#include virtual ="/test/myInclude.asp"-->
on all your pages:

/test/myInclude.asp:
<%
if Session("starte d") = "" then
Session("Referr alURL") = Request.ServerV ariables("HTTP_ REFERER")
Session("starte d") = "yes!"
end if

Hi Evertjan, Thanks for reply.

You mean to say if I put the Session("Referr alURL") =
Request.ServerV ariables("HTTP_ REFERER") in Session_OnStart it will not work.
I have also tested that and it is not working. Can you please explain why?
Because as per my knowledge the Session_OnStart event will start for each
session.

As per your suggestion I will create one .asp file with the sample code and
include the file in all pages.

Can you suggest an easy method so that I need not to modify all the pages to
include the new file?

I think your logic says that if the Session Variable "started" is empty then
only assign the Session Variable with the Referral URL else no.

But dont you think I should also crear these variables on Session_OnEnd
event? Please suggest.

Thanks

No. Unless you mean local programming in C++ or VB etc..
I think your logic says that if the Session Variable "started" is

no.
Otherwise Session("Referr alURL") would be filled with each referring
local page.
But dont you think I should also crear these variables on
Session_OnEnd event? Please suggest.

As I said, no.

1 Session variables without sessions are deleted automaticly.

2 Session_OnEnd firing is unrelyable.

3 Sessions do not end, when the user "leaves" [sloppy defined] the site,
but only when the session times out or with commands like session.abandon
or with the server closing down/restarting.

This would appear to contradict that claim:

"All the built-in objects (Application Object, ObjectContext
Object, Request Object, Response Object, Server Object, and
Session Object) are available and can be referenced in the
Session_OnStart event script."

Bottom-posting is not the alternative of top-posting, Aaron.
Re-posting garbage is always a bad habit.
Sparse inter-posting is the best.
Top-posting should be discouraged at all times on usenet.

I am sorry that you ar so easily irritated,
and thereby forgetting what 30 years of
usenet experience brought us:
Netiquette.

2 Session_OnEnd firing is unrelyable.

3 Sessions do not end, when the user "leaves" [sloppy defined] the site,
but only when the session times out or with commands like

Nowhere near as irritating as someone who breaks the flow of a thread.
