RANDOMLY - Facebook authentication for desktop applciaitons fails ...

[GoogleCodeExporter]

I am using the library version 2.1.1.
Mine is a Facebook desktop type of application.

I am attempting to perform a login using the GET and POST attempts to login 
a user to Facebook and get a session key to perform further actions such as 
posting his message on the wall etc.

This piece of code used to work flawlessly earlier, however it has started 
failing randomly since a couple of weeks.

I have got a feeling that there are some changes to the Login.php of 
Facebook platform that is causing the issue.
Are there any other updates or any other users facing this issue?

Here is the code snippet ...

            ...
            ...
            ...

            fbUrl = "http://www.facebook.com/login.php?";
            IFacebookRestClient client = new FacebookJaxbRestClient(
                    fbApiKey,
                    fbSecretKey);
            String token = client.auth_createToken();
            HttpClient http = new HttpClient();

            String szConnectionURL = fbUrl + 
                   + "api_key=" + fbApiKey + "&v=1.0&auth_token=" + token;
            GetMethod get = new GetMethod(szConnectionURL);
            http.executeMethod(get);

            //String szNonUserIdEnc = getNonUserIdEnc(get);

            PostMethod post = new PostMethod(fbUrl);
            post.addParameter(new NameValuePair("api_key", fbApiKey));
            post.addParameter(new NameValuePair("v", "1.0"));
            post.addParameter(new NameValuePair("auth_token", token));
            post.addParameter(new NameValuePair("email",userId));
            post.addParameter(new NameValuePair("pass", password));
            http.executeMethod(post);

            String sessionId = client.auth_getSession(token);
            logger.debug("Session id:" + sessionId);

            ...
            ...
            ...

Seams like I have similar problem. The results are random. I also have a 
problem with
the Facebook not recognizing my app as a Desktop, although I set it up as one.

I have the same problem. The POST method return a 200 code... is this the wrong
behaviour? In my application happen when i try with continuous login; could it 
be a
defence strategy against DoS attacks?

I have similiar problem. Sometime  i get response 200 on post method. When I 
print
the response body i get this "Cookies required". FYI, I have been send all 
cookies.
This is 2.1.1 API bug or facebook bug or defence strategy against DoS attacks?
Anybody have experience upgrading API to 3.xx version?

Hi,
we have the same problem. With experienced the same behavior. With a call to the
logout this happen less frequently. We experiment that with a login every 5 
minutes
(and a logout) we don't have problems.
Other experiences?

I have the same problem . I found some cause but no solution . The facebook 
IP(Ip 
resolved through www.facebook.com) is changed continuously . From one IP it 
always 
return response code as 302 and from other IPs it returns response code 200. It 
means when request hit One successful IP(Ip that return response code as 302) 
it 
behave like Desktop application,while for others it behave as a web application.

I have no solution . If some one have any solution please suggest.
