Dynamic 301 redirect based on url.

Hello all. I've been trying to figure out a redirect system for a site that I'm updating from classic asp to asp.net.

Currently, the site has some product search and product detail pages such as:
prodList.asp?idCategory=9
or
prodView.asp?idproduct=55

Well, what I want to do is create a 301 redirect from those pages to the new one, based on the idCategory parameter or the idproduct parameter.

I found neat little 301 redirect code

<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently" Response.AddHeader "Location", " http://www.new-url.com"
>

But I want to create a series of IF/Then statements that will redirect based on the uri parameter, and I'm not sure how to do it.

In other words, my logic is -

If WEBSITE uri = ../prodView.asp?idproduct=55
THEN
Response.Status="301 Moved Permanently" Response.AddHeader "Location", "new-url(dot)com"

I have to do this one line at a time because the Product ID's and the Category ID's will change with the new asp.net application.

In any case, any ideas? I've never written code from scratch, that's why I stink at this.

Thanks ahead of time.

 

Something like this...
I personaly would use a DB to pull the new product page from if you can instead of hard coding it.

<%
varHost = Request.ServerVariables("HTTP_HOST")
varPage = Request.ServerVariables("SCRIPT_NAME")
varQuery = Request.ServerVariables("QUERY_STRING")
If varHost = "yoursite.com" then
Response.Status="301 Moved Permanently"
  If varPage = "/prodList.asp" then
    If varQuery = "idCategory=1"
      Response.AddHeader "Location", "new_location.asp"
    Elseif varQuery = "idCategory=2"
      Response.AddHeader "Location", "new_location.asp"
    Else
      Response.AddHeader "Location", "new_location.asp"
    End If
  Elseif varPage = "/prodView.asp"
    If varQuery = "idproduct=1"
      Response.AddHeader "Location", "new_location.asp"
    Elseif varQuery = "idproduct=2"
      Response.AddHeader "Location", "new_location.asp"
    Else
      Response.AddHeader "Location", "new_location.asp"
    End If
  Else
    Response.AddHeader "Location", "unknown_list.asp"
  End If
End If
%>

Code (markup):

Hope this helps

 

COOL BEANS!!!

Thank you so much. You have no idea how many people I've asked. Seems everybody has forgotten asp.

I would love to, but like I said in my post, can't code if my life depended on it. I can script scrape like a pro, putting bits and pieces together to make it do what I want it to do, but otherwise, bupkis.

Does this work for all versions of the url? In other words, http://www and http:// and https:// ? This is the problem I've got, both www and non www AND https pages are currently listed.

Thanks.

 

red is added code
green is comments

<%
varHost = Request.ServerVariables("HTTP_HOST")
varPage = Request.ServerVariables("SCRIPT_NAME")
varQuery = Request.ServerVariables("QUERY_STRING")
[COLOR="DarkGreen"]'i dont think this is needed, but if so you can if this... too.[/COLOR]
[COLOR="Red"]varSecure = Request.ServerVariables("HTTPS")[/COLOR]

If varHost = "yoursite.com"[COLOR="Red"] OR "www.yoursite.com"[/COLOR] then
Response.Status="301 Moved Permanently"
  If varPage = "/prodList.asp" then
    If varQuery = "idCategory=1"
      Response.AddHeader "Location", "new_location.asp"
    Elseif varQuery = "idCategory=2"
      Response.AddHeader "Location", "new_location.asp"
    Else
      Response.AddHeader "Location", "new_location.asp"
    End If
  Elseif varPage = "/prodView.asp"
    If varQuery = "idproduct=1"
      Response.AddHeader "Location", "new_location.asp"
    Elseif varQuery = "idproduct=2"
      Response.AddHeader "Location", "new_location.asp"
    Else
      Response.AddHeader "Location", "new_location.asp"
    End If
  Else
    Response.AddHeader "Location", "unknown_list.asp"
  End If
End If
%>

Code (markup):

Secure pages should work as normal as the SCRIPT_NAME is the same in both cases, i added a check for WWW version as the old one didnt check.

 

Your a beast my friend. Thank you very much.

 

Hi - First I am a noob at this, so please don't laugh at my question.

Where would I insert this? on the header.asp file? I am going to try, but any help would be appreciated.

Thank you,
