How does Rails come up with the query string appended to the  
stylesheet tag?

The API does not even show a query string being appended:  
[http://api.rubyonrails.com/classes/ActionView/Helpers/AssetTagHelper.html#M001499](http://api.rubyonrails.com/classes/ActionView/Helpers/AssetTagHelper.html#M001499)

I thought it was a function of the file timestamp, but I have updated  
the file and the querystring still hasn’t changed. I just don’t want  
my users to have to refresh to force their browser to see the new  
stylesheet.

Thanks!  
Tom

I never saw a reply to this post? Is my question hard or dumb? 🙂
