Fire event before request starts?

[adambedford]

It would be great if an event could be triggered before the AJAX request starts, for things such as progress bars!

have you tried binding to the native jQuery ajax:beforeSend event?

Thanks for your response, Justin. My use case might be a little unusual but I'm wanting to start and stop progress bars for Turboboost requests in an app that also uses Turbolinks. I'm using the built-in progress bar for Turbolinks because it works better than the third party library (Nprogress), however if I bind to ajax:beforeSend for Turboboost progress bars, they trigger twice for Turbolinks requests.

If this is something you're open to accepting a PR for, I could likely get something up this weekend.
