How to update pages when Ajax get is not supported

VaR url = "newlist. asp? Id = "+ escape (ID) + math. Random ();

Due to the cache Processing Mechanism of IE, if the URL of each request in the get method is the same (the parameters are also the same), ie will call the page in the client cache, and thus cannot obtain the latest information.
Solution:
<I> when a different random number is appended to the URL, ie will assume that the request is a new page and it will be obtained from the server for real-time update. Add
Math. Random (), for example: "ajaxservice. aspx? & Requestid = "+ math. Random ();
<II> disable browser caching on the client. C # Can do this: Response. addheader ("cache-control", "No-Cache ");
If the URL parameter contains Chinese characters, you can use the Javascript escape (string) function.
