Edit: Now I need to solve this problem for real, I did a little more investigation and came up with a number of things to reduce duplicate content. I posted detailed code samples on my blog: Reducing Duplicate Content with ASP.NET MVC
First post - go easy if I've marked this up wrong or tagged it badly :P
In Microsoft's new ASP.NET MVC framework it seems there are two things that could cause your content to be served up at multiple URLs (something which Google penalize for and will cause your PageRank to be split across them):
You can set the default controller/action to serve up for requests to the root of your domain. Let's say we choose HomeController/Index. We end up with the following URLs serving up the same content:
Now if people start linking to both of these then PageRank would be split. Google would also consider it duplicate content and penalize one of them to avoid duplicates in their results.
On top of this, the URLs are not case sensitive, so we actually get the same content for these URLs too:
So, the question... How do I avoid these penalties? I would like:
Possible?
I was working on this as well. I will obviously defer to ScottGu on this. I humbly offer my solution to this problem as well though.
Add the following code to global.asax:
protected void Application_BeginRequest(Object sender, EventArgs e) { // If upper case letters are found in the URL, redirect to lower case URL. if (Regex.IsMatch(HttpContext.Current.Request.Url.ToString(), @"[A-Z]") == true) { string LowercaseURL = HttpContext.Current.Request.Url.ToString().ToLower(); Response.Clear(); Response.Status = "301 Moved Permanently"; Response.AddHeader("Location",LowercaseURL); Response.End(); } }
A great question!
