I'm trying to log into Gmail using httpwebrequest
Login Page: https://www.google.com/accounts/ServiceLogin?service=mail

I run the code below and the only cookie it gets is the GALX
Dim CookieJar = New CookieContainer

 Dim httpRequest As HttpWebRequest

 Dim httpResponse As HttpWebResponse

 Dim responseStream As Stream

 Dim responseEncoding As Encoding

 Dim responseStreamReader As StreamReader

 Dim strResponse1 As String = ""

 

CookieJar = New CookieContainer

httpRequest = CType(WebRequest.Create("https://www.google.com/accounts/ServiceLogin?service=mail"), HttpWebRequest)

httpRequest.Timeout = 5 * 10000

httpRequest.AllowAutoRedirect = True

httpRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"

httpRequest.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11 (.NET CLR 3.5.30729)"

httpRequest.KeepAlive = True

httpRequest.CookieContainer = CookieJar

httpResponse = CType(httpRequest.GetResponse(), HttpWebResponse)

responseStream = httpResponse.GetResponseStream()

responseEncoding = System.Text.Encoding.GetEncoding("utf-8")

responseStreamReader = New StreamReader(responseStream, responseEncoding)

If Not responseStreamReader Is Nothing Then

    strResponse1 = responseStreamReader.ReadToEnd

End If

It may be a lot easier if you use the .NET GMail API for your task: http://sourceforge.net/projects/gmail-api

The problem with the request is probably the domain name. Are the above cookies inside your CookieJar? Can you change the hosts to reflect "www.google.com" instead of ".google.com"?

Note that the rememberme cookie is expired.

The server is not required to bounce the cookies back. The server is, in general, in control of the cookies. As an example, it could be that if they consider you're not from Internet Explorer, that certain cookies are not valid. In which case it may simply ignore some of them. In this case you mimic Firefox, but I'm not sure if all headers are set correctly to fool the server.

All these and other problems have already been resolved in the API I mentioned above.To save yourself a lot of problems, I can strongly suggest giving it a shot.

> Are the above cookies inside your CookieJar?
hmm, I can answer that myself. Looking at your code again, I see that there are not cookies at all in the cookiejar, or perhaps you left out some of the code? Getting a meager response is then quite likely. If you want to send the cookies to the server to mimic a login of something, you'll have to send the cookies along, they're not picked up from somewhere automatically...

The code above is a snippet, I have the code for the POST part that uses the same cookiejar but to keep the code simple I wanted to use that example.  It's also not a Gmail issue.  If you try to do a GET on https://accounts.craigslist.org/

You will also not get the cookie.

The only commonality I see is that it is a secure site (https) and the web request only seems to find the cookies marked as secure: yes as indicated by web developer toolbar (pasted above from the gmail example)

If I do a GET with my browser I don't see any cookies either for that site so that's not too surprising.

> and the web request only seems to find the cookies marked as secure
I noticed the "s" but didn't make that connection. But you are right of course. Can't believe I missed that, must be tired over here or something. You just answered the question ;-)

My gut feeling is it has to do with the secure site and the non secure cookie.

For Example: https://accounts.craigslist.org/
If I do a httpwebrequest on that page with a cookie container I don't get any cookies.

Although if I go to that site with IE or FIrefox, with or without Javascript enabled, the cookie is passed to my computer.  There has to be a way to capture this cookie.
