Disabling Client Side (browser) caching & impact on AJAX

Question

Hi,

So I guess that I have 2 questions....

1. I have been asked whether client side caching has been disabled in my asp.net webforms (which it hasn't) - what is the best way of going about this?

2. Some of my webforms use AJAX - would disabling caching have any impact on AJAX?

I am using .net framework 2.


Many Thanks
Gary

if you want to store some information in  memorry then use caching.

Answer 2

Thanks for the response Lion, but I am still very unsure about caching....

The webforms contain confidential financial information and I have been asked to ensure that no data is cached on the users' browser. So I guess that I need to completely disable caching, but I am not sure of....

1. How to ensure there is no caching

2. If there is no caching, then would this affect the webform performance and/or functionality? (We dont use jQuery AJAX)

2.

if you use jQuery ajax
than
$.ajax({
  url: "test.html",
  context: document.body,
  cache:false, //it will force requested pages not to be cached by the browser.
  success: function(){
    $(this).addClass("done");
  }
});
