Updated content is not loading, when working with AJAX.

Question

Hi Friends, i am working with CHARTS.

I am using a third party tool to create charts. I am working with Asp.net AJAX, C#.

Chart loads properly during page load. The data for the chart will be saved in an xml file and csv file. Later it will be passed to chart applet through a javascript file. When i get a new set of data through new inputs, the data is getting updated in xml and csv file.

But finally when i am passing the csv and xml file path to javascript, it is displaying the page loaded content.

Thanks in advance.

I think this is a caching issue. Clear all cache and then verify.

If it is a caching issue the best possible way is to change the request string for every request. You can do this by appending a random number to the end of the querystring.

Edit:

Suppose your requect url is

var reqUrl = "http://host.com/mypage.html";

Then replace the request url string with something like

var rand = Math.random();
var reqUrl = "http://host.com/mypage.html?v0=" + rand;
