Question

In my knowledge, the RESTful WCF still has ‘.svc’ in its URL.

For example, if the service interface is like

[OperationContract] [WebGet(UriTemplate = '/Value/{value}')] string GetDataStr(string value); 

The access URI is like ‘http://machinename/Service.svc/Value/2‘. In my understanding, part of REST advantage is that it can hide the implementation details. A RESTful URI like ‘http://machinename/Service/value/2‘ can be implemented by any RESTful framework, but a ‘http://machinename/Service.svc/value/2‘ exposes its implementation is WCF.

How can I remove this ‘.svc’ host in the access URI?

In IIS 7 you can use the Url Rewrite Module as explained in this blog post.

In IIS 6 you could write an http module that will rewrite the url:

public class RestModule : IHttpModule {     public void Dispose() { }      public void Init(HttpApplication app)     {         app.BeginRequest += delegate         {             HttpContext ctx = HttpContext.Current;             string path = ctx.Request.AppRelativeCurrentExecutionFilePath;              int i = path.IndexOf('/', 2);             if (i > 0)             {                 string svc = path.Substring(0, i) + '.svc';                 string rest = path.Substring(i, path.Length - i);                 ctx.RewritePath(svc, rest, ctx.Request.QueryString.ToString(), false);             }         };     } } 

And there’s a nice example how to achieve extensionless urls in IIS 6 without using third party ISAPI modules or wildcard mapping.
