Clear cache with new versions

[edulid]

Every time I deploy a new version of my code, I have to let the users clear their browsers cache.

But is this really necessary? Would not something like the following work?

<script type="text/javascript" language="javascript" src="zedes2/sc/initsc.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Core.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Foundation.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Containers.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Grids.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Forms.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_RichTextEditor.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_Calendar.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/modules/ISC_DataBinding.js?version=1.2.8"></script> 
	<script type="text/javascript" language="javascript" src="zedes2/sc/skins/EnterpriseBlue/load_skin.js?version=1.2.8"></script> 

<script src="zedes2/sc/DataSourceLoader?version=1.2.8&dataSource=schuelerSimple"></script>

I put the version of my application in every javascript/css file. Even the DataSourceLoader.

This seems to work. Am I missing something?
Would this prevent the users to have to clear their cache when a new version is deployed?

Using smartGWT 4.1p power.

I do the same &version parameter when loading scripts in the host HTML page. But there is still a problem with the host HTML page itself. As long as it exists in browser cache, the &version trick is usless.
I am not sure but mayby putting in host page:
<meta http-equiv="pragma" content="no-cache">
would help? Is it right approach?

Interesting. I will put

<meta http-equiv="cache-control" content="no-cache" />

in the HTML page in order to avoid this. But wouldn't this prevent the cache of the smartGWT libraries to work ?

Isomorphic, is this the right approach?

That, or any other approach to prevent caching, such as adding the version as a path segment - this isn't really specific to SmartGWT.

Generally the bootstrap .html file should not be allowed to be cached or users will end up downloading mixed versions.
