Configuring IIS 7 for Relay Server

Configure IIS 7 to host a Relay Server.

1. Back up the applicationHost.config file (usually located in the System32\inetsrv\config\ directory).
2. In a text editor, open applicationHost.config.
3. Create a Relay Server application pool.

   Insert the following snippet in the <applicationPools> collection:

   <add name="RelayServer" queueLength="65535" autoStart="true" 
           managedRuntimeVersion="" managedPipelineMode="Integrated">
       <processModel identityType="LocalSystem" idleTimeout="00:00:00" 
               maxProcesses="20" pingingEnabled="false" 
               pingInterval="00:00:30" pingResponseTime="00:01:30" />
       <recycling disallowOverlappingRotation="true">
           <periodicRestart time="00:00:00">
               <schedule>
                   <clear />
               </schedule>
           </periodicRestart>
       </recycling>
       <failure rapidFailProtection="false" />
       <cpu resetInterval="00:00:00" />
   </add>       
   

4. Add the Relay Server application to the default Web site.

   Insert the following snippet in the <site name="Default Web Site"> element:

   <application path="/ias_relay_Server" applicationPool="RelayServer">
       <virtualDirectory path="/" 
               physicalPath="C:\Inetpub\wwwroot\ias_relay_server" />
   </application>
   

5. Enable Web extensions for Relay Server.

   Insert the following snippet in the <isapiCgiRestriction> collection.

   <add path="C:\Inetpub\wwwroot\ias_relay_server\Client\rs_client.dll" 
           allowed="true" />
   <add path="C:\Inetpub\wwwroot\ias_relay_server\Server\rs_server.dll" 
           allowed="true" />
   

6. Add Relay Server locations to the default Web site.

   Insert the following snippet in the <configuration> element.

   <location path="Default Web Site/ias_relay_server/client">
       <system.webServer>
           <handlers accessPolicy="Execute, Script">
           </handlers>
       </system.webServer>
   </location>
   
   <location path="Default Web Site/ias_relay_server/server">
       <system.webServer>
           <handlers accessPolicy="Execute, Script">
           </handlers>
       </system.webServer>
   </location>
   
   <location path="Default Web Site/ias_relay_server">
       <system.webServer>
           <security>
               <authentication>
                   <anonymousAuthentication userName="" />
               </authentication>
               <requestFiltering>
                   <requestLimits maxAllowedContentLength="2147483647" />
               </requestFiltering>
           </security>
       </system.webServer>
   </location>
   

7. Save your changes.
8. Open a Web browser, and confirm that http://localhost:80 loads the default page correctly.
