在IIS重写规则中处理可选URL参数的动态数量

我的情况如下：场所可以是多个类别的一部分，用户还可以在多个类别类型上添加过滤器，因此我的URL现在如下所示：

1. /venues/beaches/boats/themeparks （这将显示海滩，船只和主题公园的所有场地）
2. /venues/beaches/boats
3. /venues ETC。

因此，不同场所类型（海滩，船只，主题公园等）的数量既是动态的，也是可选的。如何设置我的重写规则，使categoryquerystring参数保留所有不同的场所类型，或者最好将category参数添加多次，并且如果未提供场所类型，则category只会为空/空？

所以对于URL： /venues/beaches/boats/themeparks

我会得到这个重写的URL： search.aspx?category=beaches&category=boats&category=themeparks

对于URL： /venues

我得到这个重写URL： search.aspx?category=（或太细会是：search.aspx）

我现在有这个：

<rule name="venue types">
  <match url="^venues/([a-zA-Z0-9-+']+)$"/>
  <action type="Rewrite" url="search.aspx?category={R:1}"/>
</rule>

更新

我接受了@Arindam Nayak的以下建议。

我安装了https://www.nuget.org/packages/Microsoft.AspNet.FriendlyUrls.Core/并RouteConfig.vb在App_Start文件夹中手动创建了一个文件。我添加了（作为测试）：

Public NotInheritable Class RouteConfig
    Private Sub New()
    End Sub
    Public Shared Sub RegisterRoutes(routes As RouteCollection)
        Dim settings = New FriendlyUrlSettings()
        settings.AutoRedirectMode = RedirectMode.Permanent
        routes.EnableFriendlyUrls(settings)

        routes.MapPageRoute("", "test", "~/contact.aspx")

    End Sub
End Class

在global.aspx.vb我补充说：

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

当我转到时www.example.com/test，它现在可以正确地将我重定向到contact.aspx。（请注意：URL重写-因此规则web.config或rewriteRules.config文件-优先于RouteConfig.vb！）

我快到了，因此www.example.com/test可以正确地重定向到file，contact.aspx但这www.example.com/test/boats/outside/more/fields/are/here会引发404错误：

更新2

我添加了日志到routeConfig.vb：

    GlobalFunctions.Log("1")
    Dim settings = New FriendlyUrlSettings()
    GlobalFunctions.Log("2")
    settings.AutoRedirectMode = RedirectMode.Permanent
    GlobalFunctions.Log("3")
    routes.EnableFriendlyUrls(settings)
    GlobalFunctions.Log("4")
    routes.MapPageRoute("", "test", "~/contact.aspx")
    GlobalFunctions.Log("5")

And these lines are all executed. Now something strange is happening: routeConfig.vb seems to only be executed once. So:

1. I build my app.
2. I goto /test URL
3. the lines are logged and I arrive on the contact.aspx page
4. I refresh the /test page, NO lines are logged

And I also tried:

1. I build my app.
2. I goto /test/boats/outside/more/fields/are/here URL
3. the lines are logged
4. I get the aforementioned 404 error
5. I refresh the page, nothing is logged anymore

So it seems routeConfig is only ever hit once (at applicationstart?) and then never hit again. And for request /test/boats/outside/more/fields/are/here it arrives at routeConfig.vb file, but does not show contact.aspx for some reason...

update 3

I found that when I explicitly define the routes, it does work, like so:

routes.MapPageRoute("", "test", "~/contact.aspx")
routes.MapPageRoute("", "test/123", "~/contact.aspx")

So now URL /test and /test/123 work, but that is not dynamic at all as I just want to match on /test and then get the FriendlyUrlSegments.

I can't post the code online, so if it helps, here's my solution explorer:

What can I do?
