qt soap client + ASP.net Web service

Question

Hi,

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

The service consists of 3 methods: Login(user,pass) Helloworld() - this method returns info oabout athenticated user. Logout()

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

The problem begins with HelloWorld() methods. it returns null beause 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 futher with my investigation and monitored HTTP traffic coming to server from Qt cleint and .NET client.

The HTTP Header for both SOAP requests are diffeent:

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)

Content-Length: 291

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

Connection: Keep-Alive

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.
