I am trying to 301 redirect a page when a query string is present. Why? Because some websites are linking to the page with query strings and it is coming up a duplicate content. So I want ...somepage.asp?xxx=yyy&zzz=123 to 301 to somepage.asp

Any easy solutions?

Thanks...I just can't THINK today!

Does it need to carry the querystring values with it?

No. The script uses POST not GET, yet people link to it with a query string.

I used this code on a page I have that had at one time been used for affiliates that worked, but doesn't for this page???
<%
If Request.QueryString("Affid") Then
Response.Buffer = True
Response.Status = "301 Moved Permanently"
Response.AddHeader "Location", "http://www.searchbliss.com/generators.asp"
Response.Flush
Response.End
End If
%>
The query string has rank=www.someidiotsdomain.com, so when I replace "Affid" with "rank" and redirect to ...com/rank.asp I get a 404 when I use the query string, and NOT when I don't???
Thanks Chris!

If Request.QueryString("rank") <> "" Then

should work Ok

Does the script on the page try to process the request collections rather than just request.form collection only?

request.form only.

Hey Chris,
I've been racking my brain on this and all fails.

The page that works has the following at the top:
<%@ LANGUAGE="VBScript" %>
<%
If Request.QueryString("rank") Then
Response.Buffer = True
Response.Status = "301 Moved Permanently"
Response.AddHeader "Location", "http://www.searchbliss.com/rank.asp"
Response.Flush
Response.End
End If
%>

The page that doesn't has this:

<%@ LANGUAGE="VBScript" %>
<%
Option Explicit
Response.Buffer = true
Dim blnSubmitted
If Request.Form("AC") <> "" Then
blnSubmitted = true
End If
If Request.QueryString("rank") Then
Response.Status = "301 Moved Permanently"
Response.AddHeader "Location", "http://www.searchbliss.com/rank.asp"
Response.Flush
Response.End
End If
%>

If there is NO query string all is OK, but if one is present, I get a 404 error rather then the redirect???
Thanks.

The error is NOT a 404 but a 500 error

from WebBug;

Quote:

HTTP/1.1 500 Internal Server Error
Cache-Control: private
Content-Length: 19773
Content-Type: text/html
Server: Microsoft-IIS/7.0

Only problem is: Microsoft in their "wisdom" have blocked error messages from being sent to the browser in IIS 7, which is a real PITA to debug anything unless you have direct access to the server!!

What's odd is I see 500 errors genarically (set up by the host), but this error points to my custom 404 page set in the web.config file for both 404 and 403 errors???

web.config only affects .net script errors "classic" ASP error handlers are set up separately in IIS management.

Do you have RDP or TS access to the server (or Plesk maybe) to make changes to the custom error pages?

No I don't have access Chris...why won't this simple 301 work on this page, but work on others! Sorry, had to vent that.

Ok set up test pages on my local server (IIS7 on Win7 Ultimate) the error is a type mismatch

This

Code:

If Request.QueryString("rank")  Then

should be

Code:

If Request.QueryString("rank") <> "" Then

"If Request.QueryString("rank") Then" would expect "rank" to be a boolean value NOT a string.

Thanks Chris! It works perfectly. I tried this before to no avail, then realized this time I hadn't cleared the cache, and bingo...it works! I changed this on the other page as well (why the other worked there is beyond me) but I wanted it correct.

Hava a beer on me!
