Question

I’m loading a view page via an $.ajax() call with jQuery. I’m explicitly setting the “cache” option to true. Nowhere in the application are we using $.ajaxSetup() to specify otherwise.

Here’s the ajax request setup:

$(".viewDialogLink").click(function() {
    $.ajax({
        url: $(this).attr("href"),
        dataType: "html",
        type: "GET",
        cache: true,
        success: function(data) { $("#dlgViews").html(data).dialog("open"); }
    });
    return false;
});

The response comes back successfully. The dialog opens, and some content displays.

HOWEVER

There are script tags in the returned html. For example:

<script type="text/javascript" src="http://../jsapi/arcgis/?v=1.4"></script>

Now – in the response text, these look normal. But the actual browser requests for these scripts, as seen from FireBug, include a cache-breaker parameter in the query string. They look like:

http://serverapi.arcgisonline.com/jsapi/arcgis/?v=1.4&_=1264703589546.

None of the other resources in the loaded html – css or images – include the cache breaker in their request.

What is going on? How do I turn this cache breaker off?

Answer 1

I was able to replicate your issue on my test server. I then changed from jquery 1.3.2 to 1.4.1. With Jquery 1.4.1 it doesn’t add the cache-breaking string.

 <script type="text/javascript" src="jquery-1.4.1.min.js"></script>

Of course, using 1.4.1 might not be an option for you.
