qt soap client + ASP.net Web service

I'm writing Qt client for ASP.NET web service with FORMS based authentication.

The service consists of 3 methods:

Every thing working fine on the dot.net client with CookieContainer.

The problem begins with HelloWorld() methods. it returns null because I can't access server session.

I'm doing the following:

from the response of Login() request I'm getting the cookies which are sent to client: 

QNetworkAccessManager *manager = http.networkAccessManager();
cookie = manager->cookieJar();

When sending the second soaprequest for HelloWorld method I adding these cookies to QtSoapHttpTransport http:

http.networkAccessManager()->setCookieJar(cookie)

but the request which is going from server is empty.

I moved further with my investigation and monitored HTTP traffic coming to server from Qt client and .NET client.

The HTTP Header for both SOAP requests are different:

This is Request coming from .NET client 

POST /test/service1.asmx HTTP/1.1
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.3053)
VsDebuggerCausalityData: uIDPoyhZznNkbItPkJSR3EA+zEIAAAAAUkpe7URduE6nmhnT8f uQeqCQBMlX0zxCm65yW4ZPBkUACQAA
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://localhost/test/HelloWorld"
Host: localhost:8080
Cookie: MyAuthenCookie=DC7620DA79E080FECA37AC6866BF2690D57 B37443506F0D7EEA9DF209827360894D80D37E1B121D73EE44 766BDAEE16BA3FB0E8B95ADB1252AB00A76706930ACDC87CF9 F26744B7E9E3EB7FBB3812997
Content-Length: 291
Expect: 100-continue

and this is Request coming from Qt SOAP client:

POST /test/Service1.asmx HTTP/1.1
Content-Type: text/xml;charset=utf-8
SOAPAction: http://localhost/test/HelloWorld
Content-Length: 350
Cookie: MyAuthenCookie=9AFB2B22EE78D19DFD52BD2193A3D71627C F7303C15E4354E43CC2F31AECBDFFAD09176AA45F33B35C3C3 73891F1FE994580E8EE70FD4D01507670743138E74E152CFF4 EB3C37D90D3A7A0E272A804C3
Connection: Keep-Alive
Accept-Encoding: gzip
User-Agent: Mozilla/5.0
Host: localhost:8080

Does any body have any idea what might be the problem and hoe to solve it?

How can I modify Headers for HTTP POST request in QtSoapHttpTransport object in order to make it identical to .NET request?

Thank you in advance, Danny.

Are you running IIS or the ASP.NET Development server?

I was able to recreate a similar problem where everything worked fine using ASP.NET Development server but under IIS the session was null.

One thing to look for is when you invoke the session-enabled-service you should see the ASP.NET_SessionId being set in the response headers

Set-Cookie: ASP.NET_SessionId=5vxqwy45waoqma45lbbozj45; path=/; HttpOnly
Set-Cookie: MyAuthenCookie=510969D70201B358F8B0BBEEE7E79316B7ABCCC74312B0BD678DA4BE90E5C51CD6E7CDCA486DDB41BCBF489DB7280B3B979FD70B78D7F63B03C33431ADDAFDCA; expires=Mon, 07-Dec-2009 06:41:04 GMT; path=/; HttpOnly

To get sessions working under IIS, I had to add the following to web.config under system.web:

<sessionState mode="InProc" cookieless="false" timeout="20" />
<httpModules>
  <add name="Session" type="System.Web.SessionState.SessionStateModule" 
</httpModules>

This was under Windows 2003.
