The best way to do this would be to try and simulate the steps using HttpClient in the same way as a browser does.
If you have Mozilla Firefox, use the HttpFox plugin and see the sequence of GET and POST request and responses when you interact with your web server using the browser. Then try to follow the same/similar sequence of GET and POSTs using the HttpClient and it should work. I had a similar problem, where after the authentication (login) to the server, there was an implicit POST from the browser using a javascript code which happened without the user having to POST anything explicitly. When I was trying to login using the HttpClient and then trying to do a GET on something else, it was failing. Then I did a similar POST (the implicit POST done by javascript) using HttpClient after the login POST and then I was able to proceed successfully. So, the problem is not necessarily with the HttpClient. It could be how your server likes to be interacted with....find that out and do the same using HttpClient and I am sure it will work. I have been using HttpClient to perform quite complicated series of POSTs, GETs and Redirects in my project....and it's been working fine and as expected. But I have had to find the proper sequence by observing the browser behavior first. Hope this helps...
