C# - How To Fetch Information Passed In The Url

I am trying the new feature of .NET 4.0 - url routing but not able to fetch information passed in the url. Following is the code :

GLOBAL.ASPX.CS

protected void Application_Start(object sender, EventArgs e)
{
SetRouting(RouteTable.Routes);
}
private void SetRouting(RouteCollection routeCollection)
{
routeCollection.MapPageRoute("Company",

[Code]....

Now the property mentioned above returns null even when i use Client/Google in the url. When i reset IIS and do it for first time, it returns value. Otherwise it gives null.
