Before trying to debug why I can't login, I've noticed a discrepancy.
Firefox returns a simpler HTML page and IE seems to redirect when I
just manually enter "http://hiveminder.com/=/action/BTDT.Action.Login"
into each browser.  I'm using the latest browsers on MS Vista Business
32.

I'm trying to automate the retrieval and posting of tasks using the HM
API.  So far, this is what I have in my VBA module:

Option Explicit
Private Enum WinHttpRequestOption
  WinHttpRequestOption_UserAgentString
  WinHttpRequestOption_URL
  WinHttpRequestOption_URLCodePage
  WinHttpRequestOption_EscapePercentInURL
  WinHttpRequestOption_SslErrorIgnoreFlags
  WinHttpRequestOption_SelectCertificate
  WinHttpRequestOption_EnableRedirects
  WinHttpRequestOption_UrlEscapeDisable
  WinHttpRequestOption_UrlEscapeDisableQuery
  WinHttpRequestOption_SecureProtocols
  WinHttpRequestOption_EnableTracing
  WinHttpRequestOption_RevertImpersonationOverSsl
  WinHttpRequestOption_EnableHttpsToHttpRedirects
  WinHttpRequestOption_EnablePassportAuthentication
  WinHttpRequestOption_MaxAutomaticRedirects
  WinHttpRequestOption_MaxResponseHeaderSize
  WinHttpRequestOption_MaxResponseDrainSize
  WinHttpRequestOption_EnableHttp1_1
  WinHttpRequestOption_EnableCertificateRevocationCheck
End Enum

Public Function DoLogin()
Dim oReq As WinHttpRequest, uMsg$
Set oReq = New WinHttp.WinHttpRequest

Const HTTPREQUEST_SETCREDENTIALS_FOR_SERVER = 0
Const HTTPREQUEST_SETCREDENTIALS_FOR_PROXY = 1

oReq.Option(WinHttpRequestOption_EnableHttpsToHttpRedirects) = CVar
(True) 'added to see if prob fixed:not fixed
oReq.Option(WinHttpRequestOption_SslErrorIgnoreFlags) = &H3300 'added
to see if prob fixed:not fixed

oReq.Open "GET", "http://hiveminder.com/=/action/BTDT.Action.Login",
False
'oReq.setRequestHeader "Cookie", "JIFTY_SID_HIVEMINDER=$COOKIE"
oReq.send
'Debug.Print oReq.getAllResponseHeaders
'Debug.Print oReq.responseText

 With oReq
     .Open "post", "http://hiveminder.com/=/action/BTDT.Action.Login",
False
     .setRequestHeader "Content-Type", "application/x-www-form-
urlencoded"
     .SetCredentials "myem...@gmail.com", "mypassword",
HTTPREQUEST_SETCREDENTIALS_FOR_SERVER
     uMsg = "address=myem...@gmail.com&password=mypassword"
    .send uMsg
    Debug.Print oReq.statusText
    Debug.Print oReq.getAllResponseHeaders
    Debug.Print oReq.responseText
End With
End Function

   'http.setRequestHeader "Cookie", "JIFTY_SID_HIVEMINDER=$COOKIE"
' may need to duplicate to get around bug
'    .setRequestHeader "Content-Type", "application/x-www-form-
urlencoded"
'    .setRequestHeader "Content-Type", "multipart/form-data"
'    uMsg = uMsg & "&J:A:F:F-remember-
auto-69933bbaccf747a70b9ac88281ba64bd-1=0"
'    uMsg = uMsg & "&remember=1"
'    uMsg = uMsg & "&token="

I would appreciate any help.  I a new REST user and am not that
familiar with HTTP and surrounding protocols.
