When doing web testing using Watin, it is not trivial to be able to do a POST request to the server. However, with the help this article on microsoft.com, I was able to figure out how. I ended up with writing this class:

\n
public class Navigator\n{\n    private IE _ie;\n\n    public Navigator(IE ie) { _ie = ie; }\n\n    public void Post(Uri baseUri, params KeyValuePair<string, object>[] postData)\n    {\n        object flags = null;\n        object targetFrame = null;\n        object headers = \"Content-Type: application/x-www-form-urlencoded\" + Convert.ToChar(10) + Convert.ToChar(13);\n        object postDataBytes = MakeByteStreamOf(postData);\n        object resourceLocator = baseUri.ToString();\n        IWebBrowser2 browser = (IWebBrowser2)_ie.InternetExplorer;\n        browser.Navigate2(ref resourceLocator, ref flags, ref targetFrame, ref postDataBytes, ref headers);\n        _ie.WaitForComplete();\n    }\n\n    private static byte[] MakeByteStreamOf(KeyValuePair<string, object>[] postData)\n    {\n        StringBuilder sb = new StringBuilder();\n        if (postData.Length > 0)\n        {\n            foreach (KeyValuePair<string, object> postDataEntry in postData)\n            {\n                sb.Append(postDataEntry.Key).Append('=').Append(postDataEntry.Value).Append('&');\n            }\n            sb.Remove(sb.Length - 1, 1);\n        }\n        return ASCIIEncoding.ASCII.GetBytes(sb.ToString());\n    }\n}
\n

For example, I can use it like so:

\n
using (IE ie = new IE())\n{\n    Navigator navigator = new Navigator(ie);\n    navigator.Post(new Uri(\"http://www.foo.com/\"), new KeyValuePair<string, object>(\"p\", 1));\n    Assert.AreEqual(\"OK\", ie.Text);\n}
