How can we maintain State in Webservices

Q

Do webservice have state ?

✍: Guest

A

Webservices as such do not have any mechanism by which they can maintain state. Webservices can access ASP.NET intrinsic objects like Session, application and so on if they inherit from “WebService” base class.

<%@ Webservice class="TestWebServiceClass" %>
Imports System.Web.Services
Public class TestWebServiceClass
Inherits WebService
<WebMethod> Public Sub SetSession(value As String)
session("Val") = Value
End Sub
end class

Above is a sample code which sets as session object called as “val”. TestWebserviceClass is inheriting from WebService to access the session and application objects.
