Table 10-1 : Properties of the WebMethod Attribute Property Description TransactionOption.RequiresNew)> [C#] [WebMethod(TransactionOption= TransactionOption.RequiresNew)] As an example of using the WebMethod attribute properties, I could modify HelloWorld as follows: <WebMethod(CacheDuration:=600)> _ Public Function HelloWorld( _ ByVal Language As String) As String And so on... Because the response to the HelloWorld request is unlikely to change, caching the response for 600 seconds (10 minutes) isn t at all unreasonable. When HelloWorld is called with Spanish as the parameter for the first time, the value will be cached. For all other requests within the next 10 minutes, HelloWorld won t actually be run; instead, the caching system in ASP.NET will supply the same response as the first request.
