Default Response.Redirect

If I use the Response.Redirect on the previous page (24ProcAddEdit.asp), the following code will not work as intended.
The third choice (Else) will happen promting the question "where did you come from".
It appears that -Request.ServerVariables("HTTP_REFERER")- does not see what the previous page was. How do I fix this?
If I remove the Response.Redirect from the previous page and use a link to manualy get to this page it works fine

'Begin HOW DID WE GET HERE
If InStr(Request.ServerVariables("HTTP_REFERER"), "24ProcAddEdit.asp") Then
     strQSMEID = Session("sv24MEID")
     Response.Write "You came from 24"
 ElseIf InStr(Request.ServerVariables("HTTP_REFERER"), "20AddNewME.asp") Then
      strQSMEID =Request.QueryString ("MEID")
      Response.Write "You came from 20"
Else
            Response.Write "Where did you come from?"
End If
'End HOW DID WE GET HERE

Response.Redirect just reroute your browser request. In other words you don't receive 200 response code from the page contains only Response.Redirect statement.
So, ServerVariables("HTTP_REFERER") will contains the address (if exists) from which you arrived to 24ProcAddEdit.asp.

HTH.

Is there an alternative to Response.Redirect?

Thanks

Yes, there is. On the server you can use Server.Transfer, which skips the step of informing the client browser.

You can also use Response.Write to push some JavaScript to the client, using location.href to force the browser to request a new page (you can pass in the old URL so in the user's experience he "goes back" while in reality (history-wise) he'' go forward).


Cheers,

Imar

I also used javascript to jump to other pages. It's much more easier. Try it.
