Firefox and IE image cache

I'm having some trouble with the firefox and ie cache, on my website the user can make a qu开发者_如何学Cery with a form, and this query returns a picture, but depending on which radio button is selected, it'll return a different picture, and it works just like that on chrome, but in IE and firefox, the same image is always returned, it only changes when i reopen the browser, can you guys give me some light on how to make this work?

Thanks to everyone, i solved my problem by putting and unique url each time i made the ajax call.

    <?php $date = date("H:i:s");  
echo '<a href="web/WEB-INF/classes/lineChart.php?id='.$date.'" title="Chart" class="chart">'; echo '<img src="web/WEB-INF/classes/lineChart.php?id='.$date.'" alt="">' ?></a>

Not sure the language you are using to code with, but regardless I am sure the strategy will work across the board. I pass an arbitrary value in the query string, something like a GUID or the datetime stamp. This will force a fresh load as the URL will be unique.

I use ASP.NET MVC which I then set a optional parameter in my route, which the controller method ignores. I then set my URL via JavaScript:

d = new Date();
$('.thumbnail').attr('src', $('.thumbnail').attr('src') + d.getTime());

The solution I needed was unique, so this is probably not similar to what you are trying to resolve. However, it should get the point across.

do private browsing in Firefox and see if image is changes successfully and problem is with cache memory or with the code

Given a unique can be the solution, but you have to watch the length in the string can keep growing, now, you can use this option at the begining of your code

$.ajaxSetup({ cache: false });

this will disable caching.
