HTTP Module causing problem with Google Cache

Question

I have a live site ( I can't provide the URL ). It is on sharepoint 2007. The pages were having a URL, later that was modified. I wrote a http module and used response.redirect() to navigate user to the correct page.

But since the site was live previously; on searching on google.com, it shows the old URL only. Though the redirection works fine. I need to change the cached URL to new URL.

How can I do that ?

Answer 1

You need to understand the different redirect codes - by itself response.redirect() just redirects a browser (or bot) to another address.

You should have been issuing a 301 redirect then Google and other services (its been roumered that there are a few other games in town) would have eventually removed the old URL and replaced with the new URL and all your 'link juice' would be kept.

If you need to change the URL of a page as it is shown in search engine results, we recommended that you use a server-side 301 redirect. This is the best way to ensure that users and search engines are directed to the correct page. The 301 status code means that a page has permanently moved to a new location.

ASP.NET code for this

Response.Status = "301 Moved Permanently" 
Response.addheader "Location", "http://www.newdomain.com/newurl/" 
Response.end
