JS caching issue with JSP

Question

I've been getting duplicated values in my database from what I believe is from my call to my JS file. I need some verification, that the way I'm generating a new JS version number is right.

Integer verCount = 0;


<script src="include/test.js?version=<%=verCount++ %>"></script>

Thanks.

Try this:

<script src="include/test.js?version=<%= (new Date()).getTime() %>"></script>

A timestamp should be unique each time don't worry about keeping a count. This will cause the js file to be reloaded each time.
