Random Querystring to avoid IE caching

by

Assuming you are using jQuery, instead of using $.get or $.getJson, use the more generic $.ajax and explicitly set the cache value to false. The following is an example:

$.ajax({
        url: "/Controller/Action",
        cache: false,
        type: "GET",
        dataType: "json",
        success: function(data, textStatus) {
                         alert("success");
                 }
    });

A little more code required (not much though) than using .getJson or .get but will solve the problem cleanly without appending random numbers.
