OneWay=true causes exception

[Roger Down]

I have used the SoapDocumentMethod(OneWay=true) on a web service.

Inside all my web services, I want to know who is accessing the respective
web service methods.

So I used the following two lines for this:

HttpContext httpContext = HttpContext.Current;
string userHostAddress = httpContext.Request.UserHostAddress;

When using this on a web service method not using the OneWay=true attribute,
everything works fine.

But on those web service methods where OneWay=true is added, I get the
following exception...:

Object reference not set to an instance of an object.
at
System.Web.Hosting.ISAPIWorkerRequestInProc.GetAdditionalServerVar(Int32
index)
at System.Web.Hosting.ISAPIWorkerRequestInProc.GetServerVariable(String
name)
at System.Web.Hosting.ISAPIWorkerRequest.GetRemoteAddress()
at System.Web.HttpRequest.get_UserHostAddress()


Is this by design or is this a bug ?

Are there other ways of getting the client ip address when using the
OneWay=true ?

Best of regards...
