codeigniter - list message using ajax refresh -

hi want list emails using context io.but times returns 0 messages , show blank page.so decided using ajax.

step1 :first take count of messages step2 : check if count>0 step 3: if count>0 =>list message step 4 : else again take count , repeat step 3 , 4 

my code is,

 $(function() {       var contid='<?php echo $_get['contextio_token'];?>';       $("#ajaxloader").html('<img src="<?php echo base_url();?>images/ajax-loader.gif" style="width:60px;">');       $.ajax({       type:"post",       url:"<?php echo base_url();?>index.php/gmailcontrol/countcontext",       data:"contxtid="+contid,       success:function(result){       if(result>0)       {     viewcontextio();      }       else       {             refreshcontext();       }        }});      });     function refreshcontext(){           var contid='<?php echo $_get['contextio_token'];?>';       $("#ajaxloader").html('<img src="<?php echo base_url();?>images/ajax-loader.gif" style="width:60px;">');       $.ajax({       type:"post",       url:"<?php echo base_url();?>index.php/gmailcontrol/countcontext",       data:"contxtid="+contid,       success:function(result){//alert(result);       if(result>0)       {viewcontextio(); }       else       {           settimeout(refreshcontext, 10000);       }        }});     } function viewcontextio() {      var contid='<?php echo $_get['contextio_token'];?>';   $("#ajaxloader").html('<img src="<?php echo base_url();?>images/ajax-loader.gif" style="width:60px;">');       $.ajax({   type:"post",   url:"<?php echo base_url();?>index.php/gmailcontrol/view_contextiomsg",   data:"contxtid="+contid,   success:function(result){//alert(result);     $("#ajaxloader").html('');    $("#contextmsgcnt").html(result);   }});  } 

but times takes more 30 refresh , got 500 internal server error. think problem of server overloading.is correct logic or other solution?any 1 please me

if you're not seeing messages when using 1 of api libraries there's problem account connection. many requests server can cause email provider throttle access account outside services.

if you're still having problems email @ support@context.io.
