How does asp.net generate a scriptResource.axd url?
<p>I am trying to ensure that stale images/js/css files in a cache will not be used after deploying a new version of an asp.net web application.</p>

<p>I'm currently looking in to the js aspect of this.  First, ALL of my own scripts are registered through the System.Web.UI.ScriptManager with normal urls to js files.  So, I've subclassed the ScriptManager and I tack a ?ver='x.x.x.x' on the end of the script url.  I don't see any problem with that for my scripts with normal urls, however there are always a lot of ScriptResource.axd references and I am concerned about these scripts.</p>

<p>So, for example, lets say in my next version I update the AjaxControlToolkit dll.  Will the scriptResource.axd urls be different from the urls used by the previous AjaxControlToolkit?  The scriptResources.axd look pretty funky to me, so I am hoping they are generated with a hash of the assembly or something?  I've been through a ton of literature on scriptResource.axd, but I haven't found anything on this topic.  Anyone have any ideas?</p>

<p>Thanks for reading.</p>
