Yes -- definitely using the correct SID value each time.

Here is onbeforenavigate2 data it is adding to a tmemo:

Postdata:
username=bea&password=[removed]&redirect=&login=Log+in
TheURL:
http://gemdev.com/auctions/login.php?sid=6a3e11611bcc35e1636ce9a2b8c67662
TheFlags:
0
TheTargetFrameName:

TheHeaders:
Content-Type: application/x-www-form-urlencoded

-- 

Tried both \r\n and \r\n\r\n.  The former gives headers that match manual form submission.

-- 

this is what code looks like:

   utils.WebPostData(bro,Edit1->Text, // http://gemdev.com/auctions/login.php?sid=6a3e11611bcc35e1636ce9a2b8c67662
        Edit2->Text); // username=bea&password=[removed]&redirect=&login=Log+in  
// tried both Log+in and Log%20in

//////////// below is from article
::WebPostData(TCppWebBrowser * CppWebBrowser, String sURL, String sPostData)
{
  BSTR bstrHeaders = NULL;
  TVariant vFlags = {0}, vTargetFrameName={0}, vPostData={0}, vHeaders={0};
  LPSAFEARRAY psa;
  LPCTSTR cszPostData = sPostData.c_str();
  UINT cElems = lstrlen(cszPostData);
  LPSTR pPostData;
  LPVARIANT pvPostData;

  bstrHeaders = SysAllocString(L"Content-Type: application/x-www-form-urlencoded\r\n");
  if (!bstrHeaders){
    Application->MessageBox("Could not allocate bstrHeaders", "Warning", MB_OK | MB_ICONWARNING);
    return;
  }

  V_VT(&vHeaders) = VT_BSTR;
  V_BSTR(&vHeaders) = bstrHeaders;

  pvPostData = vPostData;

  if(pvPostData){
    VariantInit(pvPostData);

    psa = SafeArrayCreateVector(VT_UI1, 0, cElems);
    if(!psa){
      return;
    }

    SafeArrayAccessData(psa, (LPVOID*)&pPostData);
    memcpy(pPostData, cszPostData, cElems);
    SafeArrayUnaccessData(psa);

    V_VT(pvPostData) = VT_ARRAY | VT_UI1;
    V_ARRAY(pvPostData) = psa;
  }

   CppWebBrowser->Navigate((TVariant)sURL, &vFlags, &vTargetFrameName, &vPostData, &vHeaders);

}
