Question

我在我的网络应用程序中使用Flexigrid。当用户添加或删除记录时，将调用$（“＃displays”）。flexReload函数，但它在IE中不起作用。我必须重新启动IE或手动清除浏览器的缓存。任何的想法？提前谢谢。

有两种方法可以解决这个问题

**Server side solution:**  Set the HTTP headers of the response to avoid returning response from cache.

In HTML: (in the header)

<META HTTP-EQUIV=”Cache-Control” CONTENT=”no-cache”>
<META HTTP-EQUIV=”expires” CONTENT=”0″>

In PHP: (in the script)

header(”Cache-Control: no-cache, must-revalidate”);
header(”Expires: Mon, 26 Jul 1997 05:00:00 GMT”);

In JSP: (before writing to the output stream)

response.setHeader(“Cache-Control”,”no-cache”);
response.setDateHeader (“Expires”, 0);

**Client side solution:** (1) Make HTTP POST call — only HTTP GET calls are served from cache or (2) Make sure the HTTP GET URL is different every time.

(1) Make HTTP POST call –
set method=”POST” and handle the call appropriately

(2) Append a unique parameter to the HTTP GET call so that the URL is different every time. A unique time stamp is a good choice.
The following sample code, may do the job:

var timeStampForNocache:Date = new Date() ;
params.noCacheControlVar = timeStampForNocache.getTime().toString() ;
I have named the parameter “noCacheControlVar”. You can name it anything else you please. The name does not matter. What matters is that the timestamp makes the HTTP GET URL unique.

快乐编码!!!
