Read file through Qlik Sense extension

[champsQlik]

Trying to read a file through a QS-extension object ,Extension Js script can read file in Qlik Sense dekstop version but on server it's not recognizing file when server domain is provided ,

Question 1 : Can we directly call server path as in Case 2& 3 below?

Question 2 : Can we use folder connection on QS server in JS script to access file?

   var filenm = 'http://localhost:4848/Extensions/myChart/abc.log;  // CASE 1 : SUCCESS when in QS Desktop it works
           
   var filenm = 'C:/Log/abc.log;  // CASE 2: Failed while pointing to other directory in QS dekstop
   
   var filenm = 'https://qliksense-test.xyz.com/Extensions/myChart/abc.log;  // CASE 3: Failed on server 

                 d3.tsv( filenm, function(data) { 
                                 return {
                                    Timestamp: data.Timestamp,
                                    ActiveUsers: data.ActiveUsers ,
                                    Users: data.Users,                                 
                               };
                                               
                         }, function(error, rows) {
                                if (error) { //if error is not null,
                                        console.log('error: '+ error);
                                } else if (index < rows.length) {
                                        yVal1=rows[index].ActiveUsers;
                                        yVal2=rows[index].Users;
                                        ++index;     
                                 }
                                    else {
                                        //duration(10000);
                                      }
                         });
