Question

There’s so much stuff on this online but no one seems to be able to answer this… Hopefully someone here will be!

So i have a WCF web service hosted at godaddy.com. Everything works great when i try accessing it using:

http://**www.**domain.com/DataService.svc

problem is when i remove the www i.e.

http://domain.com/DataService.svc

Here’s my web.config servicemodel section:

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="DataServiceBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="DataServiceBehavior"
      name="DataService">

    <endpoint address="" binding="basicHttpBinding" contract="IDataService"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>

Here’s my ServiceReferences.ClientConfig

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IDataService" maxBufferSize="2147483647"
                maxReceivedMessageSize="2147483647">
                <security mode="None" />
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://www.domain.ca/DataService.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IDataService" contract="Web.IDataService"
            name="BasicHttpBinding_IDataService" />
    </client>
</system.serviceModel>

My service is using a CustomServiceFactory

public class CustomServiceHostFactory : ServiceHostFactory
{
    /// <summary>
    /// A custom method to eliminate multiple base addresses from the IIS host creation process
    /// </summary>
    /// <param name="serviceType">The service type to be created</param>
    /// <param name="baseAddresses">A list of the base addresses</param>
    /// <returns>A service host</returns>
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        if (baseAddresses.Length > 1)
        {
            ServiceHost customServiceHost =
                new ServiceHost(serviceType, baseAddresses[1]);
            return customServiceHost;
        }

        return new ServiceHost(serviceType, baseAddresses[0]);
    }
}

Basically what i would like is my WCF webservice to be reachable whether the user enters domain.com or http://www.domain.com into his (or her) browser.

Any help will be greatly appreciated!

ps. Running IIS 7 with ASP 3.5

Thnaks!

You’re running across a cross domain issue. See here for a list of reasons as to why it happens. As it turns out “www” and no-www are different domains even though they don’t seem like it. You’ll need to add a cross domain file. See Tim’s blog for good info
