Passing querystring Ids URL Routing using namespace system.web.Routing

Question

I'm new to URL routing.

Case 1: I can implement URL Routing for URL:/content/category.aspx mapped to /Reservation

Case 2: I'm not quite sure how to handle the query string values.

For example:

URL:/content/category.aspx?SID=5&CID=191

I want this to map to: /Reservation

Code written for Case 1:

Global.asa

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
    RegisterRoutes(RouteTable.Routes)
End Sub

Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
    Dim urlPattern As String
    Dim Reservation As Route
    urlPattern = "Reservation/"
    Reservation = New Route(urlPattern, New JRouteHandler("~/content/category.aspx"))
    RouteTable.Routes.Add("Reservation", New Route("Reservation", New JRouteHandler     ("~/content/category.aspx")))
End Sub

Http Handler

Public Sub New(ByVal virtualPath As String)
    _virtualPath = virtualPath
End Sub

Public Function GetHttpHandler(ByVal requestContext As RequestContext) As IHttpHandler Implements IRouteHandler.GetHttpHandler
    If (Not UrlAuthorizationModule.CheckUrlAccessForPrincipal(_virtualPath, requestContext.HttpContext.User, requestContext.HttpContext.Request.HttpMethod)) Then
        requestContext.HttpContext.Response.StatusCode = CInt(Fix(HttpStatusCode.Unauthorized))
        requestContext.HttpContext.Response.End()
    End If

    Dim display = TryCast(BuildManager.CreateInstanceFromVirtualPath(_virtualPath, GetType(Page)), name)

    display.pageName = TryCast(requestContext.RouteData.Values("name"), String)
    Return display
End Function

Public Interface name
    Inherits IHttpHandler
    Property pageName() As String

End Interface
