Removing .SVC from WCF REST Service

I got a mail asking question, "How could we remove .SVC from a WCF REST Service?"   

For example, instead of 

 

We need to remove, .svc extension from address of the WCF service. 

Let us say, you have a WCF REST Service up and running 

http://localhost:58230/Service1.svc/GetMessage

With output

 

Read here: How to create a WCF REST Service

To remove service extension, we will write a HTTP Module and remove the extension and rewrite the path. 

Now to remove .svc follows below steps 

1. Add a class in WCF Application project.  
2. Add the namespace System.Web 
3. Implement the class from  IHttpModule 
   
   public class Removesvc : IHttpModule 
   
   
4. Before starting of current context take the context path and rewrite the URL. 
   
    context.BeginRequest += delegate
   {
       HttpContext cxt = HttpContext.Current;
       string path = cxt.Request.AppRelativeCurrentExecutionFilePath;
       int i = path.IndexOf('/', 2);
       if (i > 0)
       {
           string a = path.Substring(0, i) + ".svc";
           string b = path.Substring(i, path.Length - i);
           string c = cxt.Request.QueryString.ToString();
           cxt.RewritePath(a, b, c, false);
       }
   };
   
   Full source code for 
   
   RemoveSvc.cs
   
   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Web;
   
   namespace WcfService7
   {
       public class Removesvc : IHttpModule
       {
           public void Dispose()
           {
           }      
           public void Init(HttpApplication context)
           {
               context.BeginRequest += delegate
               {
                   HttpContext cxt = HttpContext.Current;
                   string path = cxt.Request.AppRelativeCurrentExecutionFilePath;
                   int i = path.IndexOf('/', 2);
                   if (i > 0)
                   {
                       string a = path.Substring(0, i) + ".svc";
                       string b = path.Substring(i, path.Length - i);
                       string c = cxt.Request.QueryString.ToString();
                       cxt.RewritePath(a, b, c, false);
                   }
               };
           }
       }
   }
   
   
5. Now we need to add the HTTP Module in configuration file of WCF Service. 
   
   <system.webServer>
       <modules>
         <add name ="removesvc" type ="WcfService7.Removesvc,WcfService7"/>
      </modules>     
   </system.webServer>  
   
   Where, RemoveSvc is name of the class implementing IHttpModule and WcfService7 is the project name (namespace)
   
   Web.Config 
   
   <?xml version="1.0"?>
   <configuration>
     <system.web>
       <compilation debug="true" targetFramework="4.0" />
     </system.web>
     <system.serviceModel>
       <behaviors>
         <serviceBehaviors>
           <behavior>
             <serviceMetadata httpGetEnabled="true"/>
             <serviceDebug includeExceptionDetailInFaults="false"/>
           </behavior>
         </serviceBehaviors>
       </behaviors>
       <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
     </system.serviceModel>
    <system.webServer>
       <modules>
         <add name ="removesvc" type ="WcfService7.Removesvc,WcfService7"/>
      </modules>     
     </system.webServer> 
   </configuration>
   
   
6. Now host the service in IIS.   [Read here :  Hosting WCF Service in IIS ]

Now when you open WCF REST Service in browser, you can see you are able to  call the service without extension , 

http://localhost:4567/Service1/GetMessage
