c# - wcf rest message inspector url redirect -

i'm having trouble implementing url redirection using message inspectors wcf rest service. idea implement afterreceiverequest change incoming request nothing, , in beforesendreply, make call uri provides actual service. can think of scenario not want break clients, continue use old uris invocations, internally redirect them different uri.

for example, service contract looks like:

[servicecontract] public interface iservice1 {     [operationcontract]     [webget(uritemplate = "person/{person}")]     string greetme(string person);      [operationcontract]     [webget(uritemplate = "donothing")]     string donothing(); } 

and implementation:

public class service1 : iservice1 {     public string greetme(string person)     {         return string.format("hi {0}", person);     }      public string donothing()     {         return string.empty;     } } 

then i'm adding messageinspector endpoint behavior. afterreceiverequest of inspector this:

        public object afterreceiverequest(ref message request, iclientchannel channel, instancecontext instancecontext)         {             operationcontext operationcontext = operationcontext.current;              if (weboperationcontext.current != null && weboperationcontext.current.incomingrequest.uritemplatematch != null)             {                 uribuilder baseuribuilder = new uribuilder(weboperationcontext.current.incomingrequest.uritemplatematch.baseuri);                 uribuilder requesturibuilder = new uribuilder(weboperationcontext.current.incomingrequest.uritemplatematch.requesturi);                  operationcontext.current.incomingmessageproperties["microsoftdataservicesrooturi"] = baseuribuilder.uri.tostring();                 operationcontext.current.incomingmessageproperties["microsoftdataservicesrequesturi"] = baseuribuilder.uri.tostring() + "donothing";                 operationcontext.current.incomingmessageheaders.to = new uri(baseuribuilder.uri.tostring() + "donothing");                 operationcontext.incomingmessageproperties["via"] = new uri(baseuribuilder.uri.tostring() + "donothing");                 request.headers.to = new uri(baseuribuilder.uri.tostring() + "donothing");             }              return null;         } 

basically, want change incoming requests go donothing() operation. however, when run this, still see request makes greetme method. attached debugger , can see code in afterreceiverequest getting executed, i'm not sure why uri redirection not happen.

any ideas?
