jquery ajax calls not getting content ,but still the request is success (i.e Http status code : 200)

Hi Team,

I am facing a problem with jquery ajax call.  Every first request on the each day ,Jquery  Ajax call was not returning the data, but on subsequent request it is returning the data. 

Please find the below sample code : 


         dataType: 'json',
         type: 'post',
         async: true,
         cache: false,
         data: param,
         success: function(Data) {
     --my logic goes here
}
});

Could some one please help me out  that , what are the things i need to consider for Further investigation on this issue. (Any browser settings / tools other than fiddler)

Thanks,
Ravi Chandu
