Spry.Utils.updateContent & IE caching pls help

Question

Hi -
so ive read quite a few posts about this problem but no
single - comprehensive solution. Basically im using updateContent
to show and refresh a mini basket display on my ecom site. works
great in firefox but in IE7 the shopping basket apparently gets
cached the first time it gets updated and and then only updates the
cached version thus making it appear as if you havent actually
added anything to your cart. I know it's a cache issue cause I
clear the cache, re-updateContent, and the most current basket
state renders.
It seems like this should be documented somewhere - hopefully
someone can offer up a straightforward solution.
Cheers
Andy

Hi Andy,
By default Spry.Utils.updateContent() uses the "GET" method
for requesting a fragment from the server. What this means is that
you are at the mercy of the Browser's caching system and the
caching rules specified for that fragment by the Web Server. IE6,
not sure about IE7, also had a bug where even though the server
says don't cache my page, IE still insists on caching the page ...
a workaround was to append a query param to your URL that made the
URL unique, for example the local time:
Spry.Utils.updateContent(ele, "myfoo.php?id=12&curTime="
+ Date.now(), myCallback);
The other workaround is to use the "POST" method. Most
browsers don't cache results from a "POST" because that is what
most web applications use to fetch data that changes.
Spry.Utils.updateContent(ele, "myfoo.php?id=12", myCallback,
{ method: "POST" });
