web services - Redirect from Webmethod in Asp.Net -

am new asp.net programming, have started web project. calling webmethod aspx page using json below:

 <script type="text/javascript">      function getlogin() {         var username = document.getelementbyid('textbox1').value;         $.ajax({             type: "post",             url: "services/logservice.asmx/authenticatelogin",             data: "{'username':'" +username.tostring()+ "'}",             contenttype: "application/json; charset=utf-8",             datatype: "json",             success: function (response) {             alert(response.d)             },             error: function (xhr, status, error) {                 // alert(textstatus);                 displayerror(xhr);             }          });     }   function displayerror(xhr) {  var msg = json.parse(xhr.responsetext);  alert(msg.message);  } </script> 

and webmethod :

[webmethod]     public string authenticatelogin(string username)     {         loginbo loginbo = new loginbo();         loginbo.username = username.tostring().trim();         string result = "";         try         {             logindao logindao = daofactory.getdaofactory().getlogindao();             result = logindao.selectuser(loginbo);         }         catch (dbconnectionexception)         {             //result = "db conenction";             throw new exception("db connection down");         }          catch (invalidloginexception)         {             //httpresponse res = new httpresponse();             //httpresponse.referenceequals.redirect("~/login.aspx");             throw new invalidloginexception("login invalid");         }         catch (exception)         {             throw new exception("uanble fetch ");         }         int ctx = context.response.statuscode;         return result;     } 

after successful authentication, want redirect user aspx page.

what best practice ?

thanks samuel

add redirect success section of getlogin() function:

success:    function (response) {     alert(response.d);     windows.location.href = "http://url.for.redirect";   } 

(or use some other method redirecting within jquery/javascript).
