Redirect from Old URL to New URL link in asp.net

Here i share the code to redirect old URL link to new URL link, i have explained the case with some example

Description:

Take an example as below as old link used in website

www.dotnetcode.in/details.aspx

Now i have deleted the page details.aspx, instead of details.aspx now i am using new page   user.aspx page URL is www.dotnetcode.in/user.aspx

Normally search engine crawl our old link so it always shows our Old link in search engine result. If the user comes to our website using

Old link we have to redirect the user to the correct page i.e. to new link.

To accomplish the above case we have to add the bit of code in Global.asax file

Add the below sub function in Global.asax file

VB.NET Code:

Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)         If System.Web.HttpContext.Current.Request.RawUrl.Contains("details.aspx") Then             System.Web.HttpContext.Current.Response.Clear()             System.Web.HttpContext.Current.Response.Status = "301 Moved Permanently"             System.Web.HttpContext.Current.Response.AddHeader("Location", "http://www.dotnetcode.in/user.aspx")             System.Web.HttpContext.Current.Response.End()         End If     End Sub

  

  

C# Code:

If (HttpContext.Current.Request.RawUrl.Contains("details.aspx")) Then     {         Response.Clear();         Response.Status = "301 Moved Permanently";         Response.AddHeader("Location", "http://www.dotnetcode.in/user.aspx");         Response.End();     }
