Question

I’m having trouble with caching on my website. I have static files that should usually be cached for weeks or months, but need to be updated right away for users if I make changes to the files. To get around this, I thought of having something like:

<script src="js/masterPage.js?v=$$Number$$" type="text/javascript"></script>

Then, I need a script to change $$Number$$ into a number. It doesn’t really matter what the number is, so long as it is different every time.

I could write a script to go through my do this kind of processing, but if there is some way to do this automatically when I hit “Publish” in visual studio it would be really handy. What possibilities are there?

You don’t need to do that. You can let IIS handle it for you by sending 304 HTTP responses until your files are modified. I answered a similar question like this here. Take a look.
