Cookies get expired after first request cycle.

[GoogleCodeExporter]

What steps will reproduce the problem?
We have the following code:

List<Header> headers = new List<Header>();
headers.Add(new Header("Cookie", "Param1=Val1;Param2=Val2"));
webKitBrowser.Navigate("http://SampleUrl.com/Page1.aspx", headers);

What is the expected output? What do you see instead?
Cookies present during first request. If user clicks any link(For page2.aspx) 
in the "SampleUrl.com/Page1.aspx" page then during this request what ever 
headers we have set during the initial navigate method call are not present.

What version of the product are you using? On what operating system?
OpenWebkitSharp Version:OpenWebKitSharp 2.9 stable.
VS: 2010,
WPF,
Operating System: Windows 7 Enterprise SP1.

Please provide any additional information below.
Do we need to set headers for every navigation? If so, How to do that?
How to set cookies to webkitbrowser document?
