请问有人做过RESTful WCF的路由服务吗？

我的路由服务的配置：

<system.serviceModel>
<services>
<service behaviorConfiguration="routingData"
name="System.ServiceModel.Routing.RoutingService">
<host>
<baseAddresses>
<add baseAddress="ｈｔｔｐ：//localhost:11112"/>
</baseAddresses>
</host>
<endpoint address="hellorouter"
binding="basicHttpBinding"
contract="System.ServiceModel.Routing.IRequestReplyRouter" />
<endpoint address="hellorouter_rest"
binding="webHttpBinding"
behaviorConfiguration="RestEndPointCfg"
bindingConfiguration="webBindingHello"
contract="System.ServiceModel.Routing.IRequestReplyRouter" />
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="routingData">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="True" />
<routing filterTableName="routingTable" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="RestEndPointCfg">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<bindings>
<webHttpBinding >
<binding name="webBindingHello"></binding>
</webHttpBinding>
</bindings>
<client>
<endpoint name="HelloService" address="ｈｔｔｐ：//localhost:11113/hello" binding="basicHttpBinding" contract="*" />
<endpoint name="RestHelloService" address="ｈｔｔｐ：//localhost:11113/hello/rest" binding="webHttpBinding" contract="*" />
</client>

<routing>
<filters>
<filter name="MatchAllFilter1" filterType="EndpointAddress" filterData="ｈｔｔｐ：//localhost:11112/hellorouter" />
<filter name="MatchAllFilter2" filterType="PrefixEndpointAddress" filterData="ｈｔｔｐ：//localhost:11112/hellorouter_rest" />
</filters>
<filterTables>
<filterTable name="routingTable">
<add filterName="MatchAllFilter1" endpointName="HelloService" />
<add filterName="MatchAllFilter2" endpointName="RestHelloService" />
</filterTable>
</filterTables>
</routing>
</system.serviceModel>

客户端调用：

WebClient client = new WebClient();
client.Headers.Add("Content-Type", "application/json");
client.Headers.Add("ContentLength", requestData.Length.ToString());
byte[] responseData = client.UploadData("ｈｔｔｐ：//localhost:11112/hellorouter_rest/Say", "POST", requestData);
string result = Encoding.GetEncoding("UTF-8").GetString(responseData);
Console.WriteLine(result);

真正的服务地址是ｈｔｔｐ：//localhost:11113/hello/rest，service部分就不写了。

路由服务是ｈｔｔｐ：//localhost:11112/hellorouter_rest,客户端调用的是Say方法，所以调用地址是：ｈｔｔｐ：//localhost:11112/hellorouter_rest/Say，调用结果是：远程服务器返回错误: (404) 未找到，就是说我的ｈｔｔｐ：//localhost:11112/hellorouter_rest/Say这个地址是错的，但我不知道正确的该怎么写啊？

代码的逻辑方面没啥大问题，就是配置有错，如果不通过路由服务，我客户端直接调ｈｔｔｐ：//localhost:11113/hello/rest/Say是没错的。

我这个总是做不对，谁能帮忙指点一下或者给个例子吗？
