Where I can fine this library's and how can I use then do you have any examples which I can refer. I need to fine the solution at the earliest, did couple of search and using XMLHttpRequest was the best available and simple option to implement. But i am still confuse why doesn't XMLHttpRequest works. I am intiallizing it and then to it return undefined?
"POST" requests do not get cached so adding a timestamp is not going to make a difference in this case. For you information: there is a better way of handling the cache and there is no timestamp needed.
