I have written a bit of code that helps with versioning of js files. Essentially it spins around the current script manager and appends the javascript file path with an md5 hash of the file. So
<script src="../Javascript/Navigation.js" type="text/javascript"></script>
becomes
<script src="../Javascript/Navigation.js?md5=70D2B4D1F236C7E340D9152B9E4102C3" type="text/javascript"></script>
I think this is a fairly common thing to do (or variants of it). What I am struggling to do is pick up the css files in the app_themes folder and do the same.
How do I get in and change the css links?
