JavaScript file not reloading in browser when modified on server

asp.net, asp.net-2.0, javascript

Solution

One rather common solution (that is also used here at SO I think) is to add a query string to the url of the javascript file, containing a version number. When you change the query string, the browser will treat it as a new file and download it rather than picking it from the cache.

<script type="text/javascript" src="http://example.com/file.js?v=2"></script>

In the above example, changing `file.js?v=2` to `file.js?v=3` would force the browser to download the file, instead of loading the cached `file.js?v=2`.

Problem

So I have this ASP.Net 2.0 website that uses functions contained within a JS file. When a webpage loads the js file loads fine. But when I change something in that file on the server the changes are not propagated to user's browser. It keeps working according to the out dated file. How can I force the browser to reload the modified file from the server?
