Question

I’m creating XMLHttpRequest as follows:

function checkDependencyFormFilledStatus(appName,formName){
    var xmlhttp;
    xmlhttp=new XMLHttpRequest();
    xmlhttp.open("GET","checkFormDependency.action formName="+formName+"&applicationName="+appName,false);
    xmlhttp.send();
    var dependentFormEmptyStatus = Ext.JSON.decode(xmlhttp.responseText);
    alert(xmlhttp.responseText);
    return dependentFormEmptyStatus;
}

The response returned by the object is dependent on the database which the action class is using.

This works fine in Firefox 10.0.

But for IE7, it returns correct response only for the first time. And for the rest of the function calls, it returns the same response (no matter what changes we make in the database). It updates its response only when I close the tab and open it (not even on reloading the page).

How to make it work in IE 7?

Answer 1

Sounds like the response is being cached.

Add a psuedo-random string (e.g. a timestamp) to the end of the URI to cache burst.
