XML Web service methods that have either the System.Web.Services.Protocols.SoapRpcMethodAttribute or System.Web.Services.Protocols.SoapDocumentMethodAttribute attribute applied to them with the System.Web.Services.Protocols.SoapDocumentMethodAttribute.OneWay property of set to true, do not have access to their System.Web.HttpContext using the static System.Web.HttpContext.Current property. To access the System.Web.HttpContext, derive the class implementing the XML Web service method from System.Web.Services.WebService and access the WebService.Context property.
