ignore tzdata

[bryanhuntesl]

This project is using tzdata which downloads the latest timezone information on startup - obviously we don't want to mock this out, any idea how I can get exvcr to ignore requests to "data.iana.org" ?

In case anyone else reads this ticket, I found a workaround for the specific case of tzdata - in my config/test.exs I added the following line to prevent tzdata downloading it's updates.

config :tzdata, :autoupdate, :disabled

It would still be interesting/useful if exvcr had a means to prevent mocking of requests by hostname, I know a functionality exists for localhost but perhaps it would be nice if it were more general.

Thanks

I guess this is the place where such a thing would be implemented, let me know if such a feature is of interest to you ?
