How to ensure client has latest scripts..? 1

[tcstom]

I run ASP.NET intranet applications which use a lot of client-side Javascript all located in external .js files. If I make a Javascript change I can't guarantee my users are running the latest script (since these files are cached by the browser) so I'm always sending out a message to ask users to clear out temp internet files or refresh the relevant page. Is there any way to instruct a client browser to obtain the latest version of a script when required?

Use your server-side code to append a timestamp after the file name when you load the script in your HTML, the browser will treat it as a request to a different file and won't use the cached version:

<script type="text/javascript" src="scripts/util.js[b]?timestamp=2008-01-31[/b]"></script>
