Script to force IE8 cache behaviour

Question

in IE8, there's an option on cache developer tools called "refresh always from server". Is it possible to have some javascript or similar to force this behaviour or I have to do it always manually?

I've tried

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

but the refreshing issue in my application seems to be resolved only by checking "refresh always from server" on cache options panel.

Thanks

Pragma targets the HTTP 1.0 specification. You may want to try using Cache-Control instead. See this for more information. — Anna Brenden

If you're using jQuery, you can do:

$.ajaxSetup({ cache: false });

which has solved many IE8 caching issues for me when using jquery + ajax.

Otherwise, you could use a "cache-breaker" by appending a unique number to the end of the .js uri. Like so:

http://mysite.com/myscript.js?=_11232131231323

Of course, the unique # could be a DateTime() that is unique on every page request.
