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

问题

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

You can't do it the way you are doing. We have implemented URL Re-Writing with the help of this free third party DLL, you can achieve what you want with the help of this Tool. It can handle query strings as well. What we did was add the DLL into our solution and write rules in the web.config for URL mapping. Please try this and if you need further help let me know.
