i unable existing session in .net web service using firefox , chrome, working in ie 9 or higher.

i calling web service using .ajax call.

 [scriptmethod(responseformat = responseformat.json), webmethod(enablesession = true)]     public string getbusinesspartnerbykey(string cardcode, string dbname)     {         general.writelog("getting bp key : " + cardcode, "bp");         //if (general.company != null)         //if (session["session"]!=null)         if (!session.isnewsession) //here getting true in ie , false in firefox , chrome.         {             try             {                //do stuff              }             catch (sqlexception e1)             {                 return code.general.response("-1", e1.message, "");             }             catch (exception e1)             {                 return code.general.response("-1", e1.message, "");             }         }         else             return code.general.response("-99", "session expire", "");     } 

this javascript snippet

$.ajax({          type: "post",          url: clienturl + "/getbusinesspartnerbykey",          data: json.stringify({ cardcode: cardcode, dbname: $.session.get("dbname") }),          contenttype: "application/json; charset=utf-8;",          datatype: "json",          error: function (xhr, status, error) {                            try {                  var msg = json.parse(xhr.responsetext);                  $(this).messagebox('error', msg.message);              }              catch (e) {                  $(this).messagebox('error', xhr.responsetext);              }                return true;          },          success: function (data) {              xml = $.parsexml(data.d);              $bp = $(xml);              $businesspartner = $bp;              if ($bp.find('result').text() == '0') {                   //do success stuff                  }              }              else {                  if ($bp.find('result').text() == "-99") {                      //do session exipration stuff                  }                  else {                       $(this).messagebox('error', $bp.find('message').text());                  }              }                 }      });

issue resolved, doing tweak in global.asax file.
