java - Microsoft ISA Server Authentication in Android -

i have application in android, in reading files remote server, code reading file given below;

            uri uri = null;             try {                 uri = new uri("http://192.168.1.116/server1/users.xml");             } catch (urisyntaxexception e) {                 e.printstacktrace();             }             httpget httpget = new httpget(uri);             httpget.setheader("content-type", "application/json; charset=utf-8");             httpget.setheader("host", "192.168.1.116");              httpresponse response = null;             try {                 response = httpclient.execute(httpget);              } catch (clientprotocolexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             }              httpentity responseentity = response.getentity();             string result = null;             try {                 result = entityutils.tostring(responseentity);                 log.d("server1", result);             } catch (parseexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             } 

now remote files behind proxy (microsoft isa server) required authentication access files. please guide me how can pass authentication parameters android access files.

i have tried following codes useless,

           url uri = null;             try {                 uri = new uri("http:// 192.168.1.116/cookieauth.dll?logon");             } catch (urisyntaxexception e) {                 e.printstacktrace();             }               defaulthttpclient httpclient = new defaulthttpclient();             httpclient.getcredentialsprovider()                     .setcredentials(                             authscope.any,                             new ntcredentials(username, password, deviceip,                                     domainname));              httppost httppost = new httppost(uri);             httppost.setheader("content-type",                     "application/x-www-form-urlencoded");             list<namevaluepair> params = new arraylist<namevaluepair>();             params.add(new basicnamevaluepair("curl", "z2fserver1/users.xmlz2f"));             params.add(new basicnamevaluepair("formdir", "3"));             params.add(new basicnamevaluepair("username", "test"));             params.add(new basicnamevaluepair("password", "test"));              urlencodedformentity ent = null;             try {                 ent = new urlencodedformentity(params, http.utf_8);             } catch (unsupportedencodingexception e1) {                 // todo auto-generated catch block                 e1.printstacktrace();             }             httppost.setentity(ent);             try {                 response = httpclient.execute(httppost);                  log.i("test", response.getstatusline().tostring());                  httpentity entity = response.getentity();                  if (entity != null) {                      inputstream instream = entity.getcontent();                     result = convertstreamtostring(instream);                     log.d("isa server", result);                      instream.close();                 }              } catch (exception e) {                 e.printstacktrace();             } 

but it’s giving http1.1 500 internal server error. have tried following link same error https://stackoverflow.com/a/10937857/67381

in case use

public static defaulthttpclient getclient(string username, string password,         integer timeout) {     httpparams httpparams = new basichttpparams();     httpconnectionparams.setconnectiontimeout(httpparams, timeout);     httpconnectionparams.setsotimeout(httpparams, timeout);     defaulthttpclient rethttpclient = new defaulthttpclient(httpparams);     if (username != null) {         rethttpclient.getcredentialsprovider().setcredentials(                 new authscope(authscope.any_host, authscope.any_port),                 new usernamepasswordcredentials(username, password));     }      return rethttpclient; } 

try, may works.

p.s.

it's not isa, ms c# webservice application, maybe...
