[Mono-devel-list] Session not working in web services ?

Wed Apr 28 13:52:44 EDT 2004

It seems that the Session container is not working even in simple web services 
like this one.

Check this out: I have a file "Sum.asmx" which have a single line:
<%@ WebService Language="c#" Codebehind="Test.cs" Class="Util.Test" %>

In  bin/Util.dll  I have the class:

using System;
using System.Web;
using System.Web.Services;
using System.Web.SessionState;

namespace Util
{
   public class Test: System.Web.Services.WebService
  {
        [ WebMethod(EnableSession=true) ]
        public int AddOne()
        {

          if ( Session["counter"] == null )
          { Session["counter"]=0; }
          else
          { Session["counter"]=(int)Session["counter"]+1; }

          return (int)Session["counter"];

        } // method
  } // class
} // namespace

For testing this I'm using xsp.exe (version 0.12). After running xsp, and 
opening my konqueror, I point to the Sum.asmx service, and go to the test 
form. Then I press Invoke several time getting 0 all times. I think this is 
an error.

The examples that comes with xsp don't make use of Session, instead they use 
static variables (!?).  I modify session1.aspx this way(see below) and then 
it worked, however it's not the same case:  this is a aspx not an asmx, and 
the code is embeded in the aspx, it's not in a dll.

Thanks in advance for helping.

                uno.InnerText = String.Format ("Button clicked {0} times.",
