js & css versioning

Question

Knowing that I can version js and css files like Option 1: myJavaScript.js?v=#myVersionNumber# myCSS.css?v=#myVersionNumber# , This will make client to do a conditional GET request and best case scenario get a 304 response. I can eliminate this http request by a different versioning strategy like Option 2: myJavaScript.#myVersionNumber#.js myCSS.#myVersionNumber#.css I am wondering if there are any good reasons (assuming that both options have the same level of maintainability), that will make me stay with Option1. Thanks for the help.

Answer 1

I would argue that your not really versioning as much as controlling caching. With the second approach I would be worried about storing multiple files in the source control systems, when if you stored a single file it will accumulate a history and can be managed easier. You can then release the new file by changing the parameter in your url.
