How to prevent browser from caching
Below are ways to prevent browser from reading local cache.
1. Use "Expires" header. To tell the browser read the latest version file rather than reading local cahe, you can add code below between <head> </head> in html file.
Code:
<!-- BEGIN INSERT -->
<META HTTP-EQUIV="Expires" CONTENT="Mon, 04 Dec 1999 21:29:02 GMT">
<!-- END INSERT -->
2. Tell browser there is no cache. In you html file which containing SWF file, input code below in <body> </body>
Code:
<!-- BEGIN INSERT -->
<HEAD>
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
</HEAD>
<!-- END INSERT -->
3. Add code below to force browser downloading file from server rather than local.
Code:
<A HREF="stockPrices.htm?1">Current stock prices</A>
You can also input code to tell browser to load the latest data.
Add variable to make sure browser load the latest data:
1.
Code:
loadVariables("mypage.asp?nocache=" + random(65000), 0, "POST");
2.
Code:
loadVariables("mypage.asp?nocache=" + getTimer(), 0, "POST");
