Hi All,
i am developing an web application when i tested it on Safari browser in IOS 6 version.On every request its fetching same cache results .
Is it a browser problem.If it not help me in clearing the cache in java script/J query.

Thanks in advance

Have you explicitly set cache to false in ajax call?

  url: "test.html",
  cache: false,
  success: function(data){
    //some processing

I tried this, but it didn't work for me.

Ooops! I missed that it is IOS6! Apple ignores the rules, and uses it's own caching policy. Common workaround, is to add some fake unique parameter to query (for example current date and time).


Another option, like correctly mentioned A Patra - set to no-cache:

No Cache-Control or Expires headers = iOS6 Safari will cache
Cache-Control max-age=0 and an immediate Expires = iOS6 Safari will cache
Cache-Control: no-cache = iOS6 Safari will NOT cache

thanks Vyacheslav
It happens when you make a httpget request.actually by default cache is set to true .you need to use some attribute like:
apply this attribute to your controller or action


here the cache duration is set to 0 and nostore property says that cached data will not be stored at client side.

You can also set the following parameters in your page so that it will not get cached in the client browser

Response.Buffer = True
Response.ExpiresAbsolute = Now().Subtract(New TimeSpan(1, 0, 0, 0))
Response.Expires = 0
Response.CacheControl = "no-cache"

This is exactly iOS6 breaking change.

Safari on iOS6 will cache POSTs that have either no Cache-Control headers or even "Cache-Control: max-age=0".

I also experienced with this issue and fix as follows.
In your web service method, please add the following line

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void HelloWorld()


if you need any more information please check in following thread.[^]
