This may be a solution for those whose web servers have multiple host headers defined and each web servers may have a different set of host headers.
Since WCF services hosted in IIS can have only one Base Address so we can create a custom service factory to intercept and create a System.ServiceModel.ServiceHost for a specific type of service with a dynamic URI or base address that is from the request URL.
To do this:
1) In your .svc file:
Add the Factory attribute as the following:
<%@ ServiceHost Language="C#" Service="YourNameSpace.RssService" CodeBehind="~/App_Code/Service.cs" Factory="YourNameSpace.DynamicMultipleHostHeadersBinding" %>
2) In your Service.cs file:
Add the following class to your service.cs file:
namespace YourNameSpace
{
public class DynamicMultipleHostHeadersBinding : ServiceHostFactory
{
protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
Uri[] dynamicAddress = new Uri[1];
dynamicAddress[0] = GetDynamicURI();
return base.CreateServiceHost(serviceType, dynamicAddress);
}
Uri GetDynamicURI()
{
String hostName = String.Format("{0}{1}/YourWebApplication/Service.svc", ((String.Compare(HttpContext.Current.Request.ServerVariables["HTTPS"], "on", true) == 0) ? "https://" : "http://"), HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString());
return new Uri(hostName);
}
}
....
....
}
3) Complile and run.
Hope this helps,
