2.Create a URL routing module and Handler

...
...
...
"UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
"false"/>
...
"UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
...
"UrlRoutingHandler" preCondition="integratedMode" verb="*" path="UrlRouting.axd" type="System.Web.HttpForbiddenHandler, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

3.Define routes

void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
void RegisterRoutes(RouteCollection routes)
{
// Register a route for Categories/All
routes.MapPageRoute(
"All Categories", // Route name
"Categories/All", // Route URL
"~/AllCategories.aspx" // Web page to handle route
);
}

4.Create Handler if needed

public class ProductRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
string productName = requestContext.RouteData.Values["ProductName"] as string;
if (string.IsNullOrEmpty(productName))
return Helpers.GetNotFoundHttpHandler();
else
{
// Get information about this product
NorthwindDataContext DataContext = new NorthwindDataContext();
Product product = DataContext.Products.Where(p => p.ProductName == productName).SingleOrDefault();
if (product == null)
return Helpers.GetNotFoundHttpHandler();
else
{
// Store the Product object in the Items collection
HttpContext.Current.Items["Product"] = product;
return BuildManager.CreateInstanceFromVirtualPath("~/ViewProduct.aspx", typeof(Page)) as Page;
}
}
}
}

sir why do you need Global.asax for this, use it like below for ex for 301 permanent redirect
        "Enforce canonical hostname" stopProcessing="true">
            "(.*)" />

                "{HTTP_HOST}" negate="true" pattern="^www\.mysite\.com$" />

            "Redirect" url="http://www.mysite.com/{R:1}" redirectType="Permanent" />
