Prevent iOS 6 from Caching Ajax POST Requests
Possible Duplicate:
Is Safari on iOS 6 caching $.ajax results?
I have a hybrid application using PhoneGap
that runs fine on Android and iOS. But when I started testing in iOS 6 I noticed that I am not getting server data for most of my ajax calls - instead I was getting the cached data from previous ajax calls.
So far I have tried the following options to disable cache -
$.ajaxSetup({ cache: false });
no-cache = true
$.ajaxPrefilter(function (options, originalOptions, jqXHR) { options.data = jQuery.param($.extend(originalOptions.data||{}, { timeStamp: new Date().getTime() })); });
But none of these seems to be working. I am invoke Java action classes from my ajax calls - will it have something to do with the reason why the methods listed above are failing?

You could disable the caching on webserver level and by using timestamps in the URL.
From here
How to fix it: There are various methods to prevent caching of requests. The recommended method is adding a no-cache header.
This is how it is done.
jQuery :
Check for iOS 6.0 and set Ajax header like this.
$.ajaxSetup({ cache: false });
ZeptoJS :
Check for iOS 6.0 and set Ajax header like this.
$.ajax({
type: 'POST',
headers : { "cache-control": "no-cache" },
url : ,
data:,
dataType : 'json',
success : function(responseText) {…}
Server side
Java :
httpResponse.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");
Make sure to add this at the top the page before any data is sent to the client.
.NET
Response.Cache.SetNoStore();
Or
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
PHP
header('Cache-Control: no-cache, no-store, must-revalidate'); // HTTP 1.1.
header('Pragma: no-cache'); // HTTP 1.0.
